Anticipated traffic requirements for future metro and access applications seem to exceed the scaling capabilities of conventional intensity-modulation (IM) direct-detection (DD) systems. Various advanced DD systems, which include single-sideband modulation with digital signal-signal beating cancellation, Stokes receivers, and Kramers-Krönig receivers, have been recently proposed. These systems, which to various extents rely on the use of digital signal processing, offer increased throughput compared to IMDD systems, and require simpler optical hardware compared to coherent systems. On the other hand, coherent systems have the best cost-per-bit when Terabits per second per transceiver rates are targeted.

This workshop aims primarily to address the question of whether advanced DD systems will ever be realistically considered for commercial metro, access, and data center systems, or whether eventually coherent technology will just take over.
