Abstract :
In this paper we present linewidth measurements on a double-heterostructure AlGaAs laser diode as a function of temperature, and report on the experimentally determined Schawlow-Townes linewidth. Further, we develop a model to explain both the origin of the power-independent linewidth, and the reasons why its magnitude increases with decreasing lattice temperature
