Abstract

It was realized a few years ago that reversed biased multiple quntum wells (MQW) p-i-n diode can function as a logic switching device, the self electrooptic device (SEED)1. The general principle of the SEED operation is that photo-current generated by light absorbed in the diode may change the voltage across it, which in turn causes a change in the absorption of light in the diode. By connecting the diode to a proper load, and by tuning the light wavelength to coincide with the heavy hole (hh) exciton, a positive feedback is achieved, leading to switching and bistable behavior.
