The influence of many-body effects on the gain and linewidth of semiconductor lasers

Abstract
We employ quantum‐mechanical many‐body theory to determine both the radiative recombination spectra and the linewidth broadening factor in III‐V semiconductor diode lasers. We conclude correlation effects and the full kp band structure in our calculation. Our results clearly illustrate the manner in which many‐body effects relax momentum conservation in the recombination process.
