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.

Abstract: A method comprising: receiving a multiplexed optical signal comprising optical channels for N wavelengths, N being a positive integer greater than or equal to two; and separating the multiplexed optical signal into a first multiplexed light and a second multiplexed light, each of the first multiplexed light and the second multiplexed light having the same polarization, and each of the first multiplexed light and the second multiplexed light having N wavelengths; separating the first multiplexed light into a plurality of first lights, each having a different wavelength; separating the second multiplexed light into a plurality of second lights simultaneous with separating the first multiplexed light into the first lights, each of the second lights having a different wavelength; and generating optical parameters for each optical channel in the N wavelengths using the first light and the second light for each wavelength.
