Abstract

The model of spectral broadening involving the composition fluctuations having a normal distribution law in barrier layers of the GaAs-Al_xGa_1-xAs quantum-well system is presented. Dependence of the energy broadening on the distribution law parameters and quantum well width is determined. A method of calculation of the density of states and optical gain in undoped quantum-well heterostructures having quantum layers or quantum wires is also proposed.
