摘要： An optoelectronic apparatus where information is communicated to and from the apparatus in the optical domain, but where the apparatus includes a transmission gate advantageously interposed between successive optoelectronic gates to sequentially convey information internally in the form of electrical, rather than optical, signals. Illustratively, the transmission gate is optoelectronic and comprises two back to back p-i-n photodiodes each including a quantum well region. The first and second optoelectronic gates are S-SEEDs comprising p-i-n photodiodes also each including a quantum well region. The transmission gate is responsive to a first level of the optical control signal for substantially blocking current, and to a second level of the optical control signal for substantially passing current. Applications of the apparatus include its use in a shift register, 2.times.1 switch, 1.times.2 switch, and an exclusive OR gate.

摘要： An opto-electronic XOR gate includes a pair of diode type light sources connected back to back in parallel by a pair of input leads to which first and second electronic logic signals are applied. With only one logic signal in the high state, one of the diode-type light sources is forward biased while the other is reverse biased. With both logic signals high or low neither diode-type light source emits. A two to one fiber optic combiner (FOC) provides a single optical output which is on only when only one electrical signal is high. If an electronic output is desired, a single photodetector converts the output of the FOC to an electronic logic signal. For performing the exclusive OR operation on optical input signals, a pair of photodetectors and buffer amplifiers and connected to the input leads. For 10 to 12 GHz switching speeds laser diodes are used as the diode-type light sources. When lower switching speeds are satisfactory, light emitting diodes can be used as the diode-type light sources.

摘要： Logic circuits employ photoresponsive GaAs field effect transistors to directly drive GaAs laser diodes to provide optical output signals in response to optical input signals. Since the only electrical inputs are DC bias voltages, each such circuit can be readily decoupled, such as for use in electrically noisy environments. The optical output represents a predetermined logic condition in response to a predetermined operating current applied to the laser diode as a result of the operation of the photoresponsive device. Two photoresponsive devices may be used to apply two different operating current magnitudes to the laser diode to produce two different optical output signals.
