It is an exciting time for the field of optical communication, in large part, due to the rebirth of coherent optical communication. Pre-amplified optical communication systems enabled by the invention of EDFA have been the mainstay for research and commercialization since the demise of coherent optical communication in the early 1990s. Advances in integrated circuits and digital signal processing technologies fortunately have brought coherent optical communication to the forefront again.
