Abstract

The existence of equidistant smooth maxima series was found in the spontaneous emission spectra of stripe single-quantum-well 0.98 micrometers range lasers with a strained InGaAs active layer. Within the limits of a 200 angstrom wide general envelope the characteristic distance between maxima for different lasers varied from 20 to 40 angstrom, corresponding to 10 to 20 longitudinal Fabry-Perot cavity mode intervals. Possible physical models of observed maxima origin are considered: recombination of electrons and holes with selection rules (Delta) u equals 0, and (Delta) u equals 1, 2, ..., where u is the level number; resonant self-effect of Fabry-Perot cavity modes field via the volume of laser crystal, layers of which, including GaAs substrate, are transparent in the 0.98 micrometers wavelength range. The latter model was confirmed experimentally.
