Abstract
The results of a large-scale study of the temperature sensitivity of t he CW threshold current are presented. The well number and length are systematically varied in a set of 175 lasers, with multiple identical devices to ensure the statistical validity of the data. The results ar e analyzed using the recently proposed T-max relation. A simple model is used to derive the T-max relation and understand the experimental r esults. A correlation is found between threshold and efficiency, and t he temperature sensitivity of the threshold current density is related to the optical gain, optical loss, and current loss mechanisms within the lasers.
