Abstract
An optical receiver includes a light receiving element configured to convert an input light signal into an electric current, a current mirror circuit including a reference current side transistor and a mirror current side transistor, the transistor being connected to the light receiving element, a current-voltage conversion circuit configured to convert an output current from the transistor into a voltage and output the voltage as a light reception level monitor voltage of the light receiving element, and a current sink circuit connected to the transistor and configured to feed an electric current to the transistor.
