| 1. An optoelectronic circuit comprising:
a) a substrate;
b) a resonant cavity that is formed on said substrate and into which is injected an input optical signal, said input optical
signal including an input digital optical signal;
c) a heterojunction thyristor device, formed in said resonant cavity, that produces an output digital electrical signal corresponding
to said input digital electrical signal, said heterojunction thyristor device having at least one modulation doped quantum
well structure that defines a channel region, an anode terminal electrode, a cathode terminal electrode, and at least one
control terminal electrode that is operably coupled to said modulation doped quantum well structure; and
d) at least one current source means, operably coupled to said control terminal electrode, for drawing charge from said channel
region.
