An optoelectronic full adder using: a beam scanning laser diode

The present stage of the integration technology for optoelectronic digital computing systems is primitive, while this technology is essential for the systems to overcome electronic digital computers in the future. For example, an optical full adder is usually composed of several fundamental optical logic gates, and the number of these gates easily amounts to a prohibitive level when such adders are integrated. This difficulty will be relieved if the number of the gates composing an adder is reduced. The reduction of the gates also results in smaller size and higher operation speed of the system.
