Paper Abstract

We investigated the effects of increasing excitation on the performance of semiconductor laser amplifiers. Amplified spontaneous emission (ASE) is a limitation to the power scaling of these devices. A Rigrod analysis is used to study the effects of ASE on the gain, signal-to-noise ratio and efficiency for different values of injection current, facet reflectivity and input laser intensity. Comparisons are made between bulk and quantum well gain media.
