Abstract
An all-optical data comparator with the help of Terahertz Optical Asymmetric Demultiplexer (TOAD) is proposed. The paper describes the all-optical data comparator by using a set of all-optical full-adder and optical switch. Comparison between two binary data is required in many data processing systems. It is sometimes necessary to know whether a binary number is greater than, equal to, or less than another number. The all-optical data comparator can be used to perform a fast central processor unit using optical hardware components. In this present communication, we have tried to exploit the advantages of TOAD-based switch to design an integrated all-optical circuit which can perform data comparison operations. © World Scientific Publishing Company.
