Original Abstract Submitted
In order to achieve a drive circuit being capable of suppressing, with a simple configuration, fluctuation in optical output due to temperature, a drive circuit includes a first terminal and a second terminal being capable of connecting a semiconductor laser diode, a current monitor unit that generates first voltage monotonically decreasing relative to an increase in drive current flowing through the semiconductor laser diode connected between the first terminal and the second terminal, a reference voltage generation unit that generates second voltage monotonically decreasing relative to a rise in ambient temperature, and a control unit that controls the drive current in such a way as to reduce a difference between the first voltage and the second voltage.
