A Method to Estimate the Junction Temperature of Photodetectors Operating at High Photocurrent

Abstract

A method to estimate the junction temperature while operating at high photocurrent levels is presented. The relative responsivity change is measured at high operating current. Using a model for the temperature-dependence of the bandgap, a relation between the relative change in the output power and the internal junction temperature is derived. Good… (More)
