Description

Lasing wavelength of semiconductor lasers changes greatly as a function of temperature, primarily due to the temperature-induced change in the band gap of active region. In this theoretical study, the temperature dependence of material parameters in long wavelength semiconductor lasers based on InGaNAs/GaAs quantum well systems are investigated. The bandgap and electron effective mass of InGaNAs quantum heterostructure are calculated by using a popular model based on band anti crossing (BAC) and the temperature dependence of these parameters are expressed by using Varshni's equation. We will also discuss the effects of temperature on the peak gain of InxGa1-x NyAs1-y /GaAs quantum well structures with various In (x) and N (y) concentrations
