Abstract
The two-dimensional temperature distribution in a DH GaAs/GaAlAs laser diode under continuous operation is analysed. The dynamic thermal dif fusion equation is solved using the transmission-line modelling (TLM) method. The heating mechanisms included in the model are nonradiative recombination in the active region, partial reabsorption of generated radiation in the active region, absorption of stimulated emission in t he cladding regions, absorption of spontaneous radiation transferred t o the capping and substrate layers, Joule heating of the substrate and scattering loss at the heterojunction interfaces.
