Abstract: |
It has been a long-time goal of photonics to develop integrated circuits that parallel, to some extent, the successes of Si CMOS integrated circuits. Fundamental limitations as well as materials issues and market factors have slowed the emergence of photonic circuits with multiple functionalities and high component counts.
Recently, however, there have been significant breakthroughs in both InP- and Si-based platforms. Heterogeneous combinations of these technologies have also shown promise. This has been driven by numerous factors including Internet data demands, the push for higher performance and, simultaneously, lower cost, and the maturation of sophisticated design and fabrication technologies. This symposium will review the state of the art in this field and project evolutionary paths. The issue of whether the two primary materials approaches will compete or merge will also be addressed |

Abstract: |
The symposium will focus on real-time implementation of digital signal processing (DSP) from 10Gbit/s to 100GbE data rates, with the first session of the symposium focusing on the technology for real-time implementation, and the second session focusing on applications of DSP. In order to apply DSP at 10Gbit/s and beyond in CMOS, a highly parallel architecture is required, which in turn presents challenges for implementation. Nevertheless DSP has become a disruptive technology for optical transceivers due to advancements in microelectronics. While the DSP may be realized using a custom application specific integrated circuit (ASIC), much of the focus of the symposium will be on field programmable gate arrays (FPGA), since their processing power is now approaching that required for prototyping of architectures and algorithms.
The FPGA market is dominated by two manufacturers, Xilinx and Altera, and therefore in order to contrast the salient features the symposium will feature a case study of implementing framing and FEC for 100GbE systems using the two platforms, which will conclude the technology half of the symposium. In the second half of the symposium four applications of high speed DSP will be considered, for both conventional direct detection systems as well as next generation digital coherent communication systems. |

Abstract: |
GPON and GE-PON and point-to-point fibre are now being deployed and can deliver ~100 Mbit/s to end users. In parallel next generation technologies are being developed such as 10 Gbit/s PONs and WDM-PONs. Unless the industry identifies a killer application causing end-users to pay extra revenue for bandwidths higher than can be delivered today, then the cost of future optical access technologies must be comparable to the technologies available today. This is a significant challenge and should be a major focus for the optical research community. This symposium will:
- Discuss drivers for next generation optical access technology - Compare capability, cost and power consumption of candidate next generation PON architectures (10Gbit/s PON, WDM-PON etc.) versus each other and versus GPON/GE-PON and point-to-point Discuss enabling optical component technology for next generation optical access with a focus on cost reduction. |

Abstract: |
The ever-increasing demand for increased capacity and level of service at a lower cost are key drivers fueling the evolution of core optical networks from statically provisioned optical links interconnected with electronic switching and regeneration to more complex and flexible, optically switched mesh topologies with dynamic provisioning. The major advantages of these flexible networks include prompt and efficient system deployment and commissioning, removal of expensive and inflexible optical-electrical-optical equipment, and rapid wavelength and service provisioning. This evolution from point-to-point links to reconfigurable optical networks is enabled by many technologies, such as physical layer photonic cross connects to the control and management techniques such as GMPLS and multi-layer network design. This symposium will give an overview of the implementations, challenges and benefits of current and next generation dynamic multilayer optical mesh networks. Major network operators will detail their motivation to transition to dynamic multi-layer mesh networks and comment on the timeframe for such transitions. Component suppliers and network designers will describe current and future implementations and capabilities of these networks. |

Abstract: |
Optical technologies will play a key role in future space communication systems. This symposium will present the status of some of the latest technology developments in Europe (ESA), United States (NASA) and Japan (NICT) both in the areas of Free Space Optical Communications (e.g., second generation of optical communications terminals for optical inter-satellite links with increased data transmission rate and reduced mass, size and power consumption; the new European DRS system; the new Japanese DRS system, etc.) and for on-board Satellite Communications (e.g., on-board digital and analog communications; optical signal processing, etc.). The symposium will conclude with a panel discussion about future developments, in-orbit demonstrations, potential operational services |

Abstract: |
Growth in Internet traffic is one of the many factors driving bandwidth consumption in present-day networks. As migration to fibre-to-the-home gathers pace internationally to accommodate customer requirements, it is essential that global network capacity meets the demand. Whilst deployment of new submarine cable systems is a welcome feature in the 2009 scenario; economic considerations make the upgrade of existing routes an attractive proposition. Advanced modulation formats, such as RZ-DPSK offer a means of extending route length or upgrade from legacy 2.5 and 10Gbps date-rates. However, terrestrial links are moving towards 40 Gbps with 100 Gbps Ethernet being widely discussed. Such upgrades present major challenges for existing submarine routes whilst new-builds are attractive with possible lower equipment costs overall. On the fibre side, dispersion slope-matched fibre is now used for trans-oceanic systems to overcome the chromatic dispersion limitations of non-zero dispersion shifted fibre. However, polarization-mode dispersion and nonlinear penalties still impose severe limitations on transoceanic links at 40 Gbps and above.
What does the future hold? Is electronic dispersion compensation the complete answer? Are sophisticated signalling constellations a way forward? The symposium speakers are well-placed to give their take on future directions. A concluding panel session will invite audience involvement in this important arena. |
