Is Coherent DSP Solved? Are we Running Out of Innovation?

Sunday, 30 March, 13:00 – 15:30

Rooms 213-214 (Level 2)

Digital coherent technologies have revolutionized optical communications and used to be the dominant topic with numerous research results in OFC. However, the pace of innovation has slowed, and the volume of DSP research has dropped significantly. What is the future of research into coherent DSP? Are there any fundamental research problems left to address? Will topics like pluggable DSP require strong innovative research, or have we reached a point where we will only see minor asymptotic improvements in the future? Can new components and analog technologies reduce or eliminate the need for DSP? How much DSP will future transceivers require? Can a hybrid of analog and DSP achieve ultimate low energy consumption? Are we running out of coherent innovation?
