An optical carrier synchronization system comprising:
- a pump generator driven by a received optical signal and configured to generate a pump;
- and
- a phase-sensitive oscillator configured to receive the pump from the pump generator and amplify a carrier component of the pump to generate an optical carrier having the same phase and polarity of an optical carrier of the received optical signal, wherein the phase-sensitive oscillator comprises a loop of nonlinear optical fiber that functions as a phase-sensitive amplifier and a fiber Bragg grating configured to repeatedly reflect the carrier component from the loop of nonlinear optical fiber back to the loop of nonlinear optical fiber.
