Optical Transceiving Using Self-Homodyne Detection (SHD) and Remote Modulation

摘要

A first optical transceiver node comprises: a laser configured to emit an input optical signal; a first splitter coupled to the laser and configured to split the input optical signal into a local oscillator (LO) optical signal and an unmodulated optical signal; and a receiver coupled to the first splitter and configured to: receive the LO optical signal from the first splitter; receive a modulated optical signal from a second optical transceiver node, wherein the modulated optical signal is a modulated version of the unmodulated optical signal; and perform phase noise cancellation of the modulated optical signal using the LO optical signal.
