Abstract :
A complete model to evaluate frequency conversion due to highly nondegenerate four-wave mixing in injection locked Fabry-Perot MQW laser oscillators is presented; it includes, besides carrier density fluctuations, very fast phenomena and propagation effects. The locking conditions are analyzed by means of an approximate method based on the mean field limit. The numerical results show good conversion gain up to the THz region and a complex behavior of the frequency response near side resonances; in particular controlled injection locking allows one to achieve a wide band response for the conversion gain
