A qualitative comparison between two semiconductor laser amplifier equivalent circuit models

Two different forms of equivalent circuit models have been independently proposed for semiconductor laser amplifiers. These have interesting similarities in their equivalent circuits. A comparison is made of the models in terms of derivation, completeness, applications, and computing speed. Results from the transmission line laser model (TLLM) are presented and show the effects of input power, carrier inhomogeneities, and front facet reflectivity on two-input intermodulation distortion.<
