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 1):
An integrated coherent receiver (ICR) comprising:\n an optical signal input port configured to receive an optical signal; a local oscillator (LO) source input port configured to receive a LO source from a remote laser source; a first polarization splitter-rotator (PSR) coupled to the optical signal input port, the first PSR configured to split the optical signal into a first optical signal and a second optical signal according to a polarization of the optical signal; a second PSR coupled to the LO source input port, the second PSR configured to split the LO source into a first LO source and a second LO source according to a polarization of the LO source; a first set of splitters coupled to the first PSR, the first set of splitters upstream of a plurality of mixers and configured to receive the first and the second optical signals, respectively, and split the first and the second optical signals into a plurality of optical component signals, respectively; and a second set of splitters coupled to the second PSR, the second set of splitters configured to receive the first and the second LO sources, respectively, and split the first and the second LO sources into a plurality of LO component sources, respectively.
