OPTICAL FREQUENCY-CONVERSION USING NEARLY DEGENERATE 4-WAVE-MIXING INA DISTRIBUTED-FEEDBACK SEMICONDUCTOR-LASER - THEORY AND EXPERIMENT

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