| Abstract: | The paper presents a new kind of optical bistability consisting of an Avalanche Heterojunction Phototransistor (AHPT) and a semiconductor laser diode(LD), four operating modes of this AHPT-LD-BOD system are also discussed when it works in the stable state. When it is operating in the mode of the optical bistability, the critical triggering optical power is no more than 10uw and the output power of the ON state is larger than 1mw. The ratio of the output optical power in the ON state to that in the OFF state is greater than 4dB. Using this kind of bistable device, five kinds of fundamental optical logic gates-OR, AND, INVERTER, NOR and NAND are realized. |
