Optical frequency conversion using nearly degenerate four-wave mixing in a distributed-feedback semiconductor laser: theory and experiment

An analytical description of nearly degenerate four-wave mixing in a single-mode semiconductor laser operating above threshold is given by using the rate-equation model. The theoretical result is confirmed by the experiment measuring the power amplification of probe and conjugate waves. A 155-Mb/s frequency-shift keying optical-transmission system is demonstrated using four-wave mixing in a bulk distributed-feedback laser diode, for wavelength conversion, optical-signal amplification, and data up-streaming.<
