The III—V materials systems of GaAIAs, Gain AsP, and related compounds are very attractive for the implementation of the many different functions required in optical computing. Optical functions such as light generation, modulation, and detection can be combined with electronic functions of switching, amplification, and addressing in the same materials system. Devices that demonstrate these functions include electrically addressable 2-D surface emitting diode laser arrays, CCD addressed multiple quantum weil spatial light modulators, optical gates or neurons, and asymmetric coupled quantum well structures that demonstrate both enhanced electroabsorption and fast optical switching.
