Thermal effects are known to play an essential role in limiting a number of different aspects of the performance of certain types of semiconductor laser. There are several possible mechanisms which could lead to such limitations, nonlinear effects being crucial. The proposal is directed at the formulation of partial differential equation models which couple thermal, electrical and optical effects in a self-consistent fashion and which properly account for each of the relevant sources of heat. These models will be studied by numerical and analytical means and a detailed investigation will be made of the manner in which heating influences the behaviour of a variety of types of semiconductor laser. The results will be used to clarify the dominant mechanisms and then applied to suggest means by which laser performance could be enhanced.In particular, a novel vertically emitting distributed feedback laser currently under development in the Department of Electrical and Electronic Engineering will be modelled. There will be continual interaction between the experimental and mathematical investigations in order to asses the validity of the models and to guide the development of the device in order to optimise its behaviour.
