    • Optical frequency conversion systems and methods are described. In one aspect, an optical frequency conversion system for generating a frequency-shifted replica of an input optical signal includes a phase modulation control signal generator and an optical phase modulator. The phase modulation control signal generator receives the input optical signal and generates a phase modulation control signal characterized by a sequence of phase shift control portions synchronized to the input optical signal. The optical phase modulator receives the input optical signal and phase shifts the input optical signal in accordance with the phase shift control portions of the phase modulation control signal to generate a frequency-converted replica of the input optical signal. An optical frequency conversion method for generating a frequency-shifted replica of an input optical signal also is described.
