title: Optical logic gates employing liquid crystal optical switches.
abstract: This paper describes very simple optical logic gates consisting of liquid crystal optical switches. This technique was used to implement all possible 2-operand Boolean functions. The importance of these systems in making optical computers is discussed in terms of a binary half-adder and a flip-flop. A new algebra governing the function of these systems is also proposed.
