ABSTRACT:
This invention consists of three separate functional devices fabricated from a single monolithic semiconductor chip. The three devices may be constructed as a unit to work in concert, or any of the three devices may be constructed alone in order to perform its particular operation independently.
The three functional devices are: an optical modulator; an optical demodulator; and, an integrated optical logic device operating in unison and utilizing coherent light from a self contained laser diode for transmitting and receiving data and performing extremely high speed logical operations photonically.
