Abstract
Electron-phonon scattering rates and intersubband optical gain spectra were calculated, including the optical phonon confinement effect in A lGaAs/GaAs/AlGaAs quantum well heterostructures. Comparison of the cal culated gain spectra with those calculated using the bulk phonon appro ximation shows that details of the phonon spectrum have a strong influ ence on the intersubband optical gain.
