Abstract
The development of efficient and powerful semiconductor laser devices demands a detailed analysis of their optical properties to characterize and identify the underlying physical processes. Such an analysis enables us to evaluate the relevant effects influencing the laser properties and thus, to study them systematically in dependence of design parameters in order to find optimized structural layouts. For this purpose we have developed a microscopic many-particle model; based on the semiconductor Bloch equations the absorption or rather the laser gain of a system can be quantitatively predicted [1].
