WS1: DSP & FEC: Towards the Shannon Limit  
Room E1 Sunday, September 20, 2009 - Time: 10:00-13:00 
Organizers:  Dirk van den Borne, Nokia Siemens Networks, Germany
Takashi Mizuochi, Mitsubishi Electric Corporation, Japan

With the recent advances in digital signal processing (DSP), coherent detection is currently living its second life in the world of fiber-optics. First generation transponders using coherent detection are coming to the market, and a significant amount of research is being invested in this area. With the rise of digital signal processing as an integral part of optical communication systems, most of the complexity is shifted from the optical/analogue to the electrical/digital domain. This will fundamentally change the way we should design our systems. 

At the same time, new generations of WDM systems continue to increase the maximum capacity; either by reducing channel spacing or by increasing bit rates. This requires the use of state-of-the-art forward error correction (FEC) coding and de-coding in order to improve system margins and realize transmission over long-haul distances. In next-generation optical transmission systems, the design of DSP algorithms and FEC coding & decoding will most likely require a combined approach. This will give rise to a new level of complexity in algorithm design and implementation challenges that will be a major challenge for both industry and the research community. 

In this workshop we will discuss DSP algorithms, FEC coding & decoding, as well as their mutual interaction in high-capacity long-haul optical transmission systems. The workshop will specifically address the implementation challenges that arise in such complex mixed-signal chip designs.


Part 1: Digital signal processing

The Digital Coherent Revolution
Seb Savory,
University College London, U.K.
The combination of digital signal processing and coherent detection is causing a revolution in optical transmission systems. We will briefly chart this revolution while outlining the salient features of a digital coherent transmission system before discussing the future challenges.

Frequency Domain Equalization without Guard Interval for High-speed Transmission.
Yutaka Miyamoto, NTT Network Innovation Laboratories, Japan
Advantages of frequency domain equalization (FDE) are described for high-speed transmission at the channel rate over 100Gbit/s. We proposed and demonstrate novel FDE scheme without guard interval in high-capacity long-haul DWDM experiment.

Challenges for VLSI implementation of 100G digital coherent receivers
Hiroshi Onaka (Fujitsu, Japan) 

Coherent Optical Systems - High-End or Commodity?
Bernhard Spinnler, Nokia Siemens Networks, Germany 
Will coherent receivers have replaced noncoherent systems in optical transmission in a few years? An attempt at future prospects.


Part 2: Forward error correction

Shannon Limits for Optical Communication
Gerhard Kramer, University of Southern California, U.S.A.
Information theory gives the maximal rates for reliable communication for point-to-point and multi-point-to-multi-point channels. In this talk, we view an optical fiber network with K wavelength-division-multiplexing channels as a K-user interference network, and we review some old and new advances in coding for such channels. The question arises: can the sophisticated coding methods be implemented in optical networks?

Implementation of hard-decision FEC for next-generation 40G/100G transmission
Frank Chang, Vitesse, U.S.A.
This talk will discuss the CI-BCH eFEC approach, providing an update on the latest 40G lab results, as well as to suggest options and theoretical performance capabilities of higher overhead ratios and stronger polynomials based on continuously interleaving method. 

Reality check: Implementation of Soft-Decision FEC in a DSP LSI
Takashi Sugihara, Mitsubishi Electric Corporation, Japan
Can we implement a soft-decision FEC having a net coding gain of >10dB?
What are the problems we should solve; e.g. LSI partitioning, multi-lane distribution, and metric generation. We will take a reality check and discuss issues of implementation.

Iterative Equalisation and Forward Error Correction (FEC)
Ralph Urbansky, University of Kaiserslautern, Germany
Combining FEC coding and Viterbi-based equalisation allows to reduce considerably the influences of PMD, CD, system non-linearity and noise. Further improvements close to the channel capacity limit are achievable by iterative equalisation and FEC decoding, so-called turbo equalisation. These concepts can also be applied to coherent and OFDM fibre-optical systems.

Part 3: Challenges of high-speed mix-signal design
Hardware requirements for coherent systems beyond 100G
Timo Pfau, Alcatel-Lucent, U.S.A.
In this talk the different options to realize a system supporting 400Gb/s are reviewed. Different modulation formats are compared in terms of reach and required hardware performance, and a possible implementation with today’s state-of-the-art DSP is evaluated.

Reality check: challenges of mixed-signal VLSI design for high-speed optical communications
Ian Dedic, Fujitsu MicroElectronics, U.K.
This talk will describe some of the problems encountered in actually realising such devices which may come as unpleasant surprises, rather than the more obvious -- and expected -- difficulties such as designing high-speed CMOS circuits.

System level trade-offs in the design of a coherent receiver
Chris Fludger,
CoreOptics, Germany
Advanced signal processing techniques that were previously only possible in low-speed radio transmission are now available for high data rate light-wave communications. Linear and non-linear distortion compensation can be effectively implemented using highly parallel architectures in low-cost CMOS signal processors. We discuss the design trade-offs of coherent receivers for 40 and 100G transmission.

Future perspectives of pure CMOS technology for coherent receivers
Bruce Beggs, Nortel Networks, Canada
This presentation will review the CMOS technology roadmap and application to high bit-rate coherent optical systems. Challenges include design of higher-speed analog transducers (ADC & PLL), implementation of efficient DSP and FEC algorithms at realizable complexity/power levels, plus monolithic packaging in an ASIC.


WS2: New Directions in Fiber Technology
Room E2 Sunday, September 20, 2009 Time: 10:00-13:00 
Organizers:  Robert Lingle, Jr., OFS
David Richardson, University of Southampton

As new fabrication technologies and optical materials have been introduced over the years, appealing estimates have been made for the ultimate limits of fiber properties such as attenuation, non-linearity (both min and max), micro- and macrobending losses, control of dispersion and slope, and birefringence. New technologies discussed in past years include non-silica materials, the application of high order modes, use of air holes as a design feature, as well as advances in solid fiber design.

This workshop will focus on 1) identifying where advancing the limits on fiber performance seems most useful for key applications and 2) understanding the current view of the theoretical and practical limits for realizing such improvements, with a view toward physical intuition. The workshop will focus on cabled fibers intended for DWDM transmission.

Key Topics to be Addressed
1. What is the long term benefit of reducing loss and increasing effective area?
2. Are there other breakthrough ideas to increase the capacity of fibers?
3. What are the fundamental and practical limits to fiber loss reduction?
4. What is the optimum strategy for reducing final, deployed cable loss?
5. How resistant can a fiber be made to cable effects?
6. What are the limits, fundamental and practical, to increasing effective area?
7. Is ultra large area fiber contradictory to minimum loss in cable?
8. What are the design tradeoffs in air core fiber?
9. Are current limits to air core fiber fundamental or potentially solvable?

WS3: Optics in Computing - How much is not enough? 

Room F1 Sunday, September 20, 2009 Time: 10:00-13:00 
Organizers:  Keren Bergman, Columbia University
S. J. Ben Yoo, UC Davis

What will be the role of photonics in future Computing? The phenomenal advances in computing technology over the past two decades were enabled by Dennard scaling, whereby the power efficiency, performance, and cost-effectiveness of silicon technology tracked Moore’s Law improvements in integrating more devices on each chip.  However, the electronic device feature sizes are rapidly approaching the atomic scale, and the ‘power wall’ has put future growth of the computing industry in jeopardy. Multicore has provided a temporary respite from stagnation of CPU clock frequencies, but creates daunting challenges to programmability, and drives today’s system architectures towards extreme levels of unbalanced communication-to-computation ratios!  It is
expected that computer chips in 2020 may contain 1000 cores with ultra high-density nanoscale devices exceeding 10 TeraFlops in performance. A 10 Teraflop chip would require an interconnect bandwidth of 100 Tb/s for a balanced architecture. This is twenty times larger than the average 5 Tb/s Internet traffic in the U.S. today! 
Photonic interconnects offer a disruptive technology solution that fundamentally changes the computing architectural design considerations towards a new generation of extremely energy-efficient and balanced computing systems. Today’s optical interconnects already exist in board-to-board, and rack-to-rack communications.  What is next?  Will it penetrate into inter-chip and intra-chip communications?   How will optical reconfiguration help computing?  What will computing look like twenty years from now?  This workshop will discuss the role of optics in computing of the future.

Using an example of how optical technology could address one of the key current challenges called the memory wall, I will show which obstacles this technology must overcome from a  technical and ecosystem point of view to be selected.

Optics and the Exascale Datacenter

HP Laboratory, Bristol

Abstract: Optical technologies are the key to delivery the higher bandwidth and lower power interconnect required for future high performance computer systems. However to exploit the full promise of the technology we need to re-evaluate computer architectures to exploit the capabilities of optical interconnect. 

Bonded photonic structure incorporated into a chip
Keishi Ohashi, Masafumi Nakada,
MIRAI-Selete and NEC Corporation; Takahiro Nakamura, NEC Corporation

Abstract: One of the merits to introduce optical interconnects is to eliminate repeaters in electrical interconnects. The transition point from electrical to optical should be determined to achieve the highest cost performance. Several bonding structures of optical interconnection layers with LSI chips will be reviewed and discussed in the session.

Nano-scale silicon photonics for energy efficient interconnection networking in Exascale systems
Keren Bergman, Columbia University, New York, USA

Abstract: As chip multiprocessors scale to increasing numbers of cores and commensurate on-chip computational power, the gap between the available off-chip bandwidth that is required to appropriately feed the processors continues to widen under current memory access architectures. We examine how silicon nano-photonics offers significant benefits to problems related to off-chip signaling in three key areas of communications distance, bitrate transparency, and bandwidth density.

A photonic architecture for high-speed interconnects
H.J.S. Dorren,
Technical University Eindhoven, the Netherlands

Abstract: A photonic packet based Clos-architecture is investigated for board-to-board or rack-to-rack interconnects where low latency is key issue. It is shown that this architectures is scalable to a large number of nodes, and is capable to resolve packet contention in the wavelength domain at the expense of low latency and  packet loss. Sub-systems and devices that support such architecture are presented.

Active Photonic Routing for Computer
Ian White,
Cambridge University, UK

Abstact: Computing power is growing rapidly and placing more rigorous demands on low cost transmission technologies for short distance links. In recent years, however, a range of photonic technologies have been studied not only to allow high speed point-to-point links, but also to form networks within computers. Such technologies have grown to accommodate both routing and switching functionality. In this paper, we will present recent studies of components and subsystems which have been developed specifically to enable routing and switching. In terms of routing, we will review the performance of a high capacity backplane able to provide Tb/s aggregate shuffle routing and be directly integrated with active components on a printed circuit board. We will then extend the presentation to describe recent work on forming active optical crosspoint switches which have both uncooled performance and also high port count.


Electro-optical packaging trends for computing applications
Bert Offrein,
IBM Zurich Research Laboratory, Switzerland

Abstract: New intra-system interconnect technologies will be required to continue the performance scaling of computing systems.

Focuses are on nano-structured optical bit memory for RAM, the optical interfaces such as serial/parallel converter and optical addressor as well as architecture design of optical packet switch with small-size buffers and the performance evaluation.


"Macrochip” Computer Systems Enabled by Silicon Photonic Interconnects
John E. Cunningham, Sun Microsystems, USA 

We present a new computing system that leverages the bandwidth, density, and latency advantages of silicon photonic interconnects to enable highly compact but scaleable supercomputer systems. Our optically enabled “macrochip” is a set of contiguous, optically-interconnected chips enabled by wavelength-division multiplexed (WDM) based silicon photonics and Optical Proximity Communications. However, a macrochip requires advancement in the state of the art in optical device technology as well as new approaches to chip packaging that we discuss.


WS4: How much Energy Efficiency Can we Achieve in Next Generation Core Networks and Switches?

Room G Sunday, September 20, 2009 Time: 10:00-13:00 
Organizers:  Marina Thottan, Alcatel-Lucent
Dirk Breuer,

This workshop aims to address a wide range of issues that affect the energy efficiency and scalability of core networks and switches. The impact of core network traffic trends (the increasing prevalence of real time interactive applications and the use of cache based network services) on energy consumption and their impact on network and switch architectures will be discussed.

These trends will be understood in the context of what is possible today in terms of scaling electronic routers both in terms of capacity as well as power consumption / dissipation. The application of optical technologies to circumvent power issues as well as the possibility of optical networks assuming additional core network functionality will be explored. The goal is generate an exciting debate among service providers, content providers, vendors (both optical and IP) as well as chip suppliers regarding the evolution of the next generation core network.

ICT Networking Energy Footprint and Opportunities
Loukas Paraschis, Cisco

Abstract: The global energy consumption of the ICT networks has remained relatively small (2-3%) despite the significant global IP traffic growth (> 50% CAGR), but it has been growing primarily due to growth in the access networks, and the data-center computationally-intensive applications.  Therefore, IC and optical technology and architectural advancements are needed to contain its energy footprint.  At the same time, "smart" networking promises significant (> 10%) improvements in the overall energy consumption, primarily from advancements in "smart-grid" power distribution, transportation, and buildings. 

David Welch,

Abstract: The amount of electrical power consumed by Information and Communication Technology (ICT) systems is increasing dramatically. Modern photonic integrated circuits (PICs), which integrate multiple optical subsystems on a single chip, greatly reduce the power consumption, heat generation, and space requirements for optical transport equipment not only on a nodal basis but on a network basis, thereby yielding significant OpEx and CapEx savings.  Our presentation will explore the parameters driving power consumption and related costs in optical networks and will outline how photonic integration can reduce overall power consumption while reducing the space requirements for optical networking equipment.

Towards a scalable and flat IP core network
Thomas Thiemer
, Nokia Siemens Networks '

Abstract: The mismatch between traffic growth and router technology improvements will force architectural changes in larger IP backbones. Flat core architectures and other changes help to improve scaling and optimise capex as well as opex (power consumption).

Ryohei Urata, NTT Photonics

Abstract: An optimum combination of optical and electrical technologies will be critical for realizing a packet-switched network. At NTT, we are currently developing a hybrid optoelectronic router that combines all-optical and optoelectronic devices with CMOS electronics to effectively reduce power consumption, size, and latency of the node while at the same time, maintaining the ability to support various IP-related services. In this presentation, we will describe the router and its key optical/optoelectronic devices which allow the label processing, switching, and buffering of high-speed asynchronous arbitrary-length optical packets.

Optical access is now being deployed around the world.  Despite lots of work on standardisation of the network equipment , there are a range of different technologies being deployed : point-to-point, active Ethernet, GPON, GE-PON, FTTCab/FTTNode, HFC.  It seems there is currently no one right answer.  While most ECOC presentations on the topics focus on the network equipment, the cost of installing the fibre infrastructure is actually the dominant cost.  In this workshop companies from around the world will describe their optical access deployments with a focus on the following questions:

1) How do they install the fibre infrastructure into the access network?

2) Why have they chosen the particular network technology (point-to-point, PON etc)?

3) What technology do they use for in-home network?

WS9: Quantum Information Technologies

Room F2 Sunday, September 20, 2009 Time: 14:30-17:30
 Organizers:  Thomas Jennewein, University of Waterloo, Canada
Paul Toliver, Telcordia Technologies, USA

Quantum cryptography, or actually quantum key distribution (QKD), is the most mature application of the quantum information technologies. The first practical protocol, called BB84, was invented in 1984 and the key exchange between distant users is safeguarded by transmitting single quanta. Since then there have been many theoretical and experimental advances of QKD protocols, and the first commercial systems are already on the market. However, quantum cryptography presently faces challenges before it can achieve widespread deployment.

1) There are the technological questions, such as how to extend distances beyond metro-scale reach as well as determining which physical implementation might provide the best performance.

2) There are the questions on the commercial side, such as identifying possible markets for quantum technologies and specifying the relevant performance criteria that might be required by IT-security markets.

This workshop will foster discussions on these questions. Several keynote speakers coming from diverse areas will each briefly present their individual viewpoints, plus additional time will be reserved for questions and discussions. By bringing together relevant institutions from Industry and Academia, we plan to gain unique perspectives on future directions for QKD and its application to securing real-world networks.


Introduction to QKD
We will briefly present the history and background of quantum key distribution (QKD), and highlight the most important developments it has seen. This will provide a baseline for the state-of-the-art achievements presented in this workshop.

Quantum Key Distribution over Telecom Networks

Hugo Zbinden, University Genve
QKD has been demonstrated over up to 250 km of ultra low loss (dark) fibre in the lab. Here, we discuss the combination of the quantum channel and data traffic using a single fibre and WDM. Recent experimental results with a commercial QKD and encryption system are presented.

Practical Megabits/s Quantum Key Distribution
Z. L. Yuan, A. R Dixon, J. F. Dynes, A. W. Sharpe, A. J. Shields, Toshiba Labs
We show that InGaAs/InP avalanche photodiodes (APDs) offer a practical and cost-effective solution to high speed single photon detection in high-bit-rate quantum key distribution. Operated with a circuit that compares the output with that in the preceding period, InGaAs APDs allow high count rate (500 MHz), efficient (10-25%), low-noise (10-6-10-5 per gate) single photon detection with a repetition rate exceeding 1 GHz. Applied to quantum key distribution, the secure bit rate has exceeded 1 Mb/s for a 20km fibre link and remained at 10 kb/s for 100km. The same device has also been applied to an ultra-long distance (200km) entanglement distribution. Our results pave the way towards a high bit-rate quantum key distribution network at low cost.

Optical Networking for Quantum Key Distribution and  Quantum Communications
Thomas Chapuran,
Optical-layer networking can significantly extend the applicability of quantum communications by moving beyond dedicated point-to-point optical links, and by sharing fiber with conventional traffic. We demonstrate many of the fundamental capabilities needed, and describe an architecture with the flexibility and scalability likely to be critical for widespread deployment of quantum applications.

Marker Drivers and Requirements for Encryption and QKD in Enterprise Connectivity Applications
Christian Illmer,
ADVA Optical
The presentation will cover the question of commercial and technical requirements a sellable QKD solution would have to fulfill in order to integrate with a WDM system. Starting with the enterprise application environment the author will try to highlight important aspects like power budget, size, relative costs, OA&M interfaces, etc.

Does QKD fit to the WDM world?
Misha Brodsky, AT&T
I will start by discussing feasible multi-user QKD architectures. Then by examining the specifications of existing telecom components I'll touch upon some limitations that WDM environment imposes on quantum key distribution systems. As few examples, we will consider the coincidence rates of photon pairs separated by a wavelength selective switch in various WSS configurations.

A possible role of QKD in photonic networks
Akihisa Tomita, ERATO-SORST, JST
