The limitation on signal processes implementable using conventional semiconductor circuits
based on electric signals necessitates a revolutionary change in device structures such that
they can exploit photons or light. Herein, we introduce optoelectric logic circuits that convert
optical signals with different wavelengths corresponding to different colors into binary
electric signals. Such circuits are assembled using unit devices in which the electric current
through the semiconductor channel is effectively gated by lights of different colors. Color …
