Abstract

Wavefront superposition is a powerful technique for performing optical logic operations. In this investigation, a new technique employing wavefront superposition has been proposed to implement an optical half-adder; the experimental results are presented. Multiplexing these half-adders to perform any additions and potential hardware specifications are also discussed.
