ABSTRACT:
A semiconductor device includes a chip, a laser element formed on the chip and a heating element formed on the chip. The laser element is driven to emit a laser beam upon light-on of a laser. Upon light-off of a laser, switching is made so that the heating element is driven so as not to emit the laser beam in the normal laser beam emission direction by the laser element.
