Distributed Aggregation and Reception of a 400-Gb/s Net Rate Superchannel in a Single-Photodiode 110-GHz Kramers-Kronig Receiver

We use a distributed superchannel aggregation scheme to demonstrate ultra-wideband single-photodiode reception based on inherently polarization-aligned Kramers-Kronig carrier generation at the receiver. The impact of polarization rotations is discussed. 400-Gb/s capacity is demonstrated for optimized conditions.
