ABSTRACT:
Temperature regulation of an avalanche photodiode is obtained by internal heating, by passing a reverse current through the breakdown region of the photodiode. In operation, an empirically-derived, reverse bias potential, equal to the breakdown potential at the desired operating temperature, is applied; and when incident radiation is to be detected the reverse bias potential is temporarily lowered to an empirically-derived operating value.
