Abstract

We investigate the wavelength conversion efficiency of quantum dot semiconductor optical amplifiers using nonde-generate four-wave mixing. Further we calculate the linewidth enhancement factor as a function of the injection current and determine the effect of the carrier reservoir. The model is on the basis of semiconductor Maxwell-Bloch equations with microscopically calculated interband Coulomb scattering rates as input to the carrier dynamics between quantum dot ground and first excited state and quantum well.
