Next Generation Coherent: Architectures and Technologies

Wednesday, 14 March, 13:30-14:30
Theater III, Hall B2
Session sponsored and organized by Acacia Communications

Session Description

By leveraging the power of CMOS silicon, coherent technology has been able to accelerate reductions in cost, size, and power of optical interconnections for transport applications. New coherent products will offer data rates of 400G to 600G using a single wavelength based on 16nm and 7nm process benchmarks.  Advances in optical components are contributing, as well, with higher bandwidth and lower cost packaging technologies. This session will discuss trends in coherent architectures and technologies with an eye toward the future.  Topics to be discussed include:
  • Can data rates continue to increase at the same pace?
  • What is the value of probabilistic shaping coming into play and Shannon’s limit?
  • How can the different functions of a coherent optical interconnect be best partitioned?
  • What are the next steps in packaging and integration?
  • Can we get to smaller CMOS geometries and continue to offer the benefits of Moore’s Law?
  • Where will coherent technology be adopted in the next five years?
