ABSTRACT:
A bistable semiconductor laser device has reset light irradiation means for irradiating a reset light for stopping the delivery of a lasing light from the laser. The laser comprises an active layer comprising a gain region in which stimulated emission occurs to attain a optical gain and a saturable absorption region in which no optical gain is attained at the lasing wavelength, resetting of the laser being carried out by irradiating onto the gain region of the laser a light having a wavelength in accordance with which the irradiated light is amplified by stimulated emission thereby to reduce carriers in the gain region of the laser.
