Abstract :
An optoelectronic exclusive-OR gate has been demonstrated in high speed GaAs photoconductive switches. Optical output was achieved by gain-switching an auxiliary semiconductor laser from the electrical output of the logic device. Signal pulses shorter than 400ps were obtained with an on-off contrast ratio better than 19dB
