Scaling optical transmission systems and networks through massive spatial parallelism

While network traffic keeps increasing at exponential rates, fiber-optic communication systems are rapidly approaching fundamental as well as practical limits in capacity and power consumption. This reality holds true from sophisticated digital coherent trans-oceanic transmission systems all the way to highly integrated co-packaged optics for short-reach intra-datacenter links. We will explore scalability limitations across fiber-optic communication applications and show how massive spatial parallelism is the only way to scale communication system capacities while providing the necessary energy and cost reductions to keep the Internet scale in a viable manner.
