Abstract

The intraband relaxation time is one of the important parameters in basic properties of semiconductor lasers. Spectra of gain and spontaneous emission are deformed by the intraband relaxation (1) (2). In particular, this effect is very remarkable in quantum-well lasers (3). The spectral shape becomes smooth and broad in spite of the sharp step-like density-of-states in quantum-wells. The intraband relaxation plays an important .role also in. oscillation mode behavior.
