In high-speed computation, optics has established itself as a successful candidate. Many proposals have already been adopted for performing arithmetic, algebraic, and logic operations using light as the information carrier. We propose a new method of optical data comparison with the proper use of nonlinear material applying the 1's compliment method. The binary optical data are manipulated here properly to achieve the required result.
