ABSTRACT
The optical modal gain of ridge-waveguide single-quantum-well InGaAs/AlGaAs diode lasers with an emission wavelength of 980 nm were measured up to a temperature of 250 °C. Comparisons of the obtained gain curves with a simple semiclassical model based on the single-band envelope function theory allows straightforward curve fitting of the gain as it is used, e.g., in numeric models. As a result a simple temperature dependence of the line shape function has been deduced. © 2000 American Institute of Physics.
