ABSTRACT: Using Terahertz Optical Asymmetric Demultiplexer (TOAD) based switch we
have designed all-optical parallel half adder and full adder. The approach to
design this all-optical arithmetic circuit not only enhances the
computational speed but also is capable
of synthesizing light as input to produce desire output. The main advantage of
parallel circuit is synchronization of input which is not required. All the circuits are designed theoretically and verified
through numerical simulations.
