Abstract
An optical logic circuit which is high in operation speed, low in power dissipation, and capable of operating at room temperature, possesses a semiconductor laser biased at a constant current higher than a threshold current. A light input is injected into the laser, the light input differing in the polarization direction of its oscillation mode. The output light of the semiconductor laser has a bistability characteristic with respect to the light input.
