Modeling of gain and phase dynamics in quantum dot amplifiers

Abstract: This work shows that p-doped quantum dot lasers grown on silicon exhibit a low linewidth enhancement factor and hence a high resistance against optical feedback which

We conclude that motional narrowing in the optical spectrum of a quantum dot broadened by spectral diffu- sion occurs in the unexpected regime of low temperature and low
