摘要：
The present invention relates to an optical switch which will generate and emit a beam of light when an optical signal is directed therein, but includes means to inhibit the generation of the beam of light when a second optical signal is directed therein. The switch includes a light emitter formed of a plurality of layers of alternating opposite conductivity type which is adapted to generate the beam of light when an optical signal is directed therein. A photovoltaic inhibitor is connected to the emitter so that any current generated by the inhibitor is applied across the emitter in a manner to prevent the generation of the light in the emitter. The photovoltaic inhibitor generates the current when a second optical signal is directed therein. Depending on the external circuit, the device can be operated in either a digital (bistable) or analog mode.
