Abstract:
An integrated coherent receiver that is configured to receive an optical signal and receive a local oscillator (LO) source from a remote location. The integrated coherent receiver is configured to extract phase and frequency information carried by the optical signal using the LO source from the remote location.

Claim (Index 14):
A method for performing coherent detection, the method comprising:\n receiving, at an integrated coherent receiver, an optical signal; receiving, at the integrated coherent receiver, an LO source from a remote location; extracting, by the integrated coherent receiver, phase and frequency information carried by the optical signal using the LO source from the remote location; splitting the optical signal into a first optical signal and a second optical signal according to a polarization of the optical signal using a first polarization splitter-rotator (PSR); splitting the LO source into a first LO source and a second LO source according to a polarization of the LO source using a second PSR; splitting the first optical signal and the second optical signal into a plurality of optical component signals using a first set of splitters; splitting the first LO source and the second LO source into a plurality of LO component sources using a second set of splitters; and providing the plurality of optical component signals and the plurality of LO component signals to a plurality of mixers, the first set of splitters and the second set of splitters upstream of the plurality of mixers.
