ABSTRACT:
Optical-to-electrical logic operations may be performed employing as each logic variable a different light wavelength and providing an optical-to-electrical semiconductor converter such that each particular wavelength responsive optical energy receiving region is an updoped region bounded by a thin tunneling junction having a thickness of the order of the mean free path of a carrier in the tunneling region.
