Temperature dependence of self-pulsation in compact disc lasers

Experimental data regarding the temperature dependence of compact disc lasers are presented. The authors demonstrate, for the first time, a temperature-dependent model which has been adapted from a well established compact disc laser model. By comparing the experimental trends and calculation, they attempt to highlight the role of certain phenomena such as non-radiative recombination and charge carrier diffusion on the device behaviour. From these results they come to a number of important conclusions regarding the origin of self-pulsation in these types of laser diodes.
