Long-wavelength infrared photoinduced switching of a resonant tunneling diode using the intersubband transition

Voltage switching induced by long-wavelength infrared light from a CO/sub 2/ laser was observed using a double-barrier resonant tunneling diode (RTD) biased in the bistable region and the intersubband transition (IT) between the quantum confined states. Possible optoelectronic and all-optical switching applications involving hysteresis are proposed and discussed.<
