Abstract

Room-temperature two-element latching circuits are experimentally demonstrated using GaAs multiple-quantum-well (MQW) nonlinear etalons under single-wavelength bistable operation. Signal power gains of up to 4 and contrast ratios of 10 have been achieved at milliwatt power levels with 1-μs pulses, which will allow the construction of more complicated digital optical circuits using diode lasers as the light sources. The problems of applying these nonlinear etalons to fast optical signal processing are also discussed. Numerical simulations show that the gain vanishes as the pulse duration decreases and approaches the carrier lifetime.
