Acoustoelectronic Phenomena in Nanodimentional Heterolasers

Abstract

The effect acoustic strains of an active medium have on the spectral characteristics of the emission of quantum-well and quantum-dot heterolasers is studied experimentally and theoretically. Results obtained earlier for the effect on the emission spectrum are briefly reviewed. The polarization effects recently observed in laser structures of different compositions at various levels of the operating current above its threshold value are analyzed in detail.
