<p>An optical receiver includes a light-receiving element (11), a bias circuit (30), an output circuit (40), and a damping resistor (22). The light-receiving element (11) converts an optical signal into an electrical signal. The bias circuit (30) applies a DC bias voltage to the light-receiving element. The output circuit (40) outputs, from an output terminal, a voltage corresponding to an optical current generated by the light-receiving element (11). The damping resistor (22) is connected between the light-receiving element (11) and the output terminal in the output circuit (40) and has a resistance set to serve as a critical damping condition in combination with a junction capacitance and a lead inductance of the light-receiving element (11). <IMAGE></p> |
