Abstract
An optically integrated bistable device includes a semiconductor junction Fabry-Perot interferometer cavity and a pair of electrodes for applying a reverse-bias voltage to the junction to increase its light absorption. A capacitor is connected between one electrode and ground for eliminating spurious high-speed signals. A resistor is connected in series with the voltage source between the electrodes to decrease the back-bias in response to photocurrent for a negative feedback.
