Abstract

PURPOSE: To prevent the decrease in light emission efficiency owing to the effect of temperature and maintain the once decreased light output constant by placing a semiconductor light emitting element, a temperature detecting element, a temperature controller and a light receiving device within one package, controlling the controller with the output of the detecting element and controlling the input current to the light emitting element with the output of the photo detector.
