英文摘要	An optically controlled vertical-cavity, surface-emitting laser comprising a heterojunction, bipolar photo-transistor epitaxially grown on a substrate and a vertical-cavity, surface-emitting laser epitaxially grown on the photo-transistor. Two electrodes set up a single current path through the laser and photo-transistor. A controlling optical beam selectively illuminates the photo-transistor to turn it on, open the current path through the laser, and causing the laser to emit light. Dependent upon the electrical biasing conditions, the combination device can be used as an optical amplifier or can be made to optically latch. Further, it can be biased to operate as an AND or OR gate.
