The analytical theory of four-wave mixing in semiconductor amplifiers is developed. The theory applies to arbitrary saturation conditions. If carrier depletion and spectral hole burning are considered, the conversion efficiency is the maximum at a total input power that produces a gain compression of e−2 (approximately −9 dB), independently of the physical parameters of the amplifier.
