Abstract

PURPOSE: To suppress the level fluctuation of the output signal caused by the variation of the temperature, the secular change and others as well as to improve the output distortion by providing a feedback circuit which feeds back only the distortion component of the optical output and then varying the level of the electric signal obtained by the photo detector.
