ABSTRACT:
A light transmission circuit 20 is biased to one optical bistable region of its multistable characteristic by a bias light from a light source 29. The bias light is superimposed by plural control pulse lights, and the superimposed light is irradiated. If the light intensity of the bias light exceeds a predetermined turning point according to the light intensity of the control pulse light, the state of multiple quantum well layers 4 and 24 are changed. Then, the light transmission state of the light transmission circuit 20 changes. Hereby, after the control pulse light disappeared, the bias light is detected by a light-receiving device 30 in a different transmission state from the prior state. And, the transmission state returns to the original state by selecting suitable light intensities of the control pulse lights to be superimposed. Therefore the light transmission circuit 20 can be switched reversibly.
