HIGHLY NONDEGENERATE 4-WAVE-MIXING IN SEMICONDUCTOR-LASER OSCILLATORS

A complete model to evaluate frequency conversion that is due to highl y nondegenerate four-wave mixing in Fabry-Perot laser oscillators is p resented; propagation effects are taken into account. Simplified expre ssions are obtained in the limit of perfectly reflecting mirrors that permit analytical solutions; they are in good agreement with the resul ts of the numerical analysis. Examples of results exhibit interesting features such as a correction factor for the relaxation frequency peak , good conversion gain up to the terahertz region, and complex behavio r of the frequency response near side-mode resonances.
