Coherent technologies, where the phase of the optical carrier provides higher signal-to-noise ratios, have been used since 2010 for long-haul communications at data rates of 100Gb/s and beyond. In the near future, with the demand for even higher data throughputs, can the IMDD approaches satisfy this need? Will there be opportunities for coherent technologies? This topic has been discussed previously with many experts believing that short reach coherent technology based links are still many years away. This workshop will review recent developments and reexamine the outlook for coherent technologies.
