Modeling of optical properties for type-II semiconductor lasers — •Christoph Schlichenmaier1, Jörg Hader2, Jerry V. Molony2, Angela Thränhardt1, Mackillo Kira1, and Stephan W.

Design of advanced semiconductor laser structures demands the insightful use of compound materials consisting of many constituents. Smart alignment of heterostructure layers like type-II structures is an additional way of band gap engineering. Quantum optical modeling of electron and photon dynamics[1,2] connected with a realistic band structure explains optical properties and device performance and helps to map out the parameter space. We discuss gain, α-factors and luminescence for various systems.
