Abstract
An optical-switch driver circuit includes a pulse signal source and a voltage-applying circuit. The pulse signal source generates pulse waves that rise from a first voltage to a second voltage. The voltage-applying circuit, for one of the pulse waves, outputs a voltage higher than the third voltage, then outputs a voltage lower than the third voltage, and further outputs the third voltage.
