In this paper we present the development of mid-infrared GaAs/AlGaAs QCLs technology and discuss basic characteristics of lasers fabricated at the Institute of Electron Technology. We also show that reliable simulation methods which can deal with the

The influence of layer thickness, heterostructure design, optical confinement factor and spontaneous emission efficiency on laser parameters of GaN based quantum well optically pumped lasers is studied in wide spectral (373 - 470 nm), temperature (77

The temperature sensitivity of threshold current of double quantum well lasers is studied both theoretically and experimentally over the temperature range 77 K to 300 K. It is found that these devices behave predictably up to 160 K but that the model

Low threshold 6 - 15 m range lead salt diode lasers have been fabricated from closely lattice-matched PbSnSeTe-PbSeTe double-heterostructure layers grown on PbSnTe or PbTe substrates by liquid phase epitaxy. Temperature dependence of threshold curren
