The traveling-wave equations of four-wave mixing in semiconductor amplifiers are solved analytically including saturation of the amplifier. Excellent agreement is obtained with numerical solutions of the traveling-wave equations. The analytical model is used to analyze a highly nondegenerate four-wave mixing experiment in a bulk semiconductor amplifier.>

The time evolution of the nondegenerate four-wave mixing polarization in a semiconductor optical amplifier (SOA) is investigated theoretically by solution of the semiconductor Bloch equations, including all the relevant scattering processes. The results are in direct agreement with recent experimental measurements, showing that a treatment of coherent and incoherent effects in SOA's on the level of a microscopic theory is highly desirable.
