摘要：

The amplified spontaneous emission (ASE) of a strained quantum-well distributed feedback (DFB) laser biased below laser threshold is used to extract the gain and refractive index spectra in a systematic manner, A modified Hakki-Paoli method is used to obtain the gain and differential gain spectra, The refractive index change due to carrier injection is obtained from the shift of the Fabry-Perot peaks in the ASE spectrum, The measured ASE spectrum, gain, refractive index change, and linewidth enhancement factor are then compared with our theoretical model for strained quantum-well lasers, Our model takes into account the realistic band structure and uses the material and quantum-well dimensions directly in the calculation of the electronic and optical properties. The theory agrees very well with the experiment.
