Abstract

PURPOSE: To compensate the output fluctuation of the regular photo detector at the regular photo detector side, by comparing the output of the temperature compensating photo detector featuring the same temperature properties as the regular photo detector with the reference voltage and by changing the driving current of the regular photo detector in accordance with the active output.
