Abstract
There are reviewed the optical properties of two kind of active regions of mid infrared laser devices both grown on GaSb substrates: GaInAsSb/AlGaInAsSb type I QWs for laser diodes and InAs/GaInAsSb type II QWs for interband cascade lasers. There are presented their crucial optical properties and the related current challenges with respect to the device performances. This covers such issues as spectral tenability of the emission via the structure parameters, the band gap discontinuities, carrier loss mechanisms and oscillator strengths. For that, spectroscopic techniques have been used (photoluminescence and its temperature dependence, and photoreflectance) and combined with the energy level calculations based on effective mass approximation and kp theory. Eventually, the potential for further material optimization and prospects for the improved device performances are also discussed.
