Abstract: |
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. |

Abstract: |
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.

Abstract: |
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. |

Abstract: |
With bandwidth demand continuing to grow, operators, system vendors and component manufacturers are preparing themselves for the move to 100Gb/s. How, where and when this move will happen is subject of a lively debate. This workshop will report on the latest status of relevant IEEE, ITU and OIF standards and bring people from industry and academia together sharing their views.
- Which technologies will be used & which optical performance can be expected? - In which network area will 100 Gb/s first be introduced? - When is the 100 Gb/s introduction likely to happen? - Which will be the market drivers for 100 Gb/s rollout? These are the questions to which this workshop wants to stimulate answers and discussions. |

Abstract: |
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? |

Abstract: |
Advanced modulation formats are a powerful means for squeezing more information into a given bandwidth for transmission through optical fiber. In turn, photonic integrated circuits are a powerful means for realizing transmitters and receivers for advanced modulation formats. This workshop will explore various integration approaches, both monolithic and hybrid, and the many possible material platforms, including glasses, group III-V materials, group IV materials, and lithium niobate.
We will dig down to the bones and sinews of these approaches, exposing their strengths and weaknesses, answering questions such as which technologies may have the lowest cost? Which may consume the lowest power? Which may have the smallest footprint? Which are likely to be stepping stones and which are likely to last? |

Abstract: |
Dynamic transport networks, based on ASON-GMPLS control planes, are being deployed in carrier networks to meet growing data and video bandwidth needs efficiently and economi-cally. NG transport network integrating optical and layer 2 protocols are becoming available from system providers. Seamless interworking of control planes of multi-layer transport networks will be critical to support end to end provisioning.
This workshop will provide an overview of multi-layer control plane protocols, technologies and evaluations in progress at various labs. Examples of technologies such as Layer 1 (OTN) and Layer 2 (PBB-TE, MPLS-TP) next generation networks will be considered in detail. Also included will be insights into the work conducted by the OIF (Optical Internetworking Forum) to enable end to end, dynamically provisioned carrier-grade broadband services. |

Abstract: |
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. |
