Does Approaching Shannon Limit Leave Only Device Developments in Optical Communications?
Tuesday, 5 March, 19:30 - 21:30
Room 6D

Organizers:  David Plant, McGill University, Canada; Peter Winzer, Nokia Bell Labs, USA

Provocateurs:  To be determined.

Description: In the past 30 years, due to the advances in technologies including TDM, WDM, coding, detection, fiber and optical amplifiers, the capacity of single mode fiber has been increased by 1 million times. Today single mode fiber capacity is close to its fundamental limit, and most of system research is focused on coding and DSP technologies to close just a couple of dB gap to Shannon limit. Although SDM promises a significant increase in fiber capacity, there is still doubt on its real applications. At the same time, with the technology progress in devices and components, the cost and energy consumption per bit keep decreasing at the same speed as that in the past. Does this mean that the future of optical communications leaves only to device developments? Are there research topics in the fiber transmission that can continually scale up the capacity, spectral efficiency, or even a new defined parameter? On the other hand, the capacity in typical short-reach transmission links are still far off from Shannon limit. How do novel transmission technologies help reduce the cost and energy consumption of these links?
