ALL-OPTICAL PARALLEL HALF ADDER USING TERAHERTZ OPTICAL ASYMMETRIC DEMULTIPLEXER

Abstract

Using TOAD based switch we have designed a parallel half-adder. The approach to designing all-optical arithmetic circuits not only enhances the computational speed but is also capable of synthesizing light as input to produce the desired output. The main advantage of a parallel circuit is the synchronization of input is not required. All the circuits are designed theoretically and verified through numerical simulations .
