A METHOD OF IMPLEMENTING PHASE ENCODED OPTICAL HALF ADDER AND FULL ADDER SYSTEM

Abstract

A complete analytical model of all optical half adder and full adder is proposed based on phase encoding. This architecture consists of numbers of optical coherent mixers and mirrors. Optical switches are used only in the encoding of inputs, but no such switches are used in the processing part. So real time operation based on this proposed encoding may be achieved. The output of the system always carries the same intensity and therefore it is suitable for using in a combinational and sequential logic system.
