Abstract: | The results of low temperature (4.2K) stimulated emission and optical gain dynamics in highly photoexcited AlxGa1−xAs/As type I superlattices are presented. It was established that the increase of the pump quantum energy leads to the essential (more than one order) reduction of the stimulated emission intensity. The effect is explained in terms of quasiparticle system heating peculiarities in two-dimensional semiconductor structure. |
