Arithmetic operation is an essential task in any type of computing system. In high-speed all-optical computations, arithmetic operations are used to exploit the highest capability of optical performance. We propose a binary addition and subtraction scheme with proper accommodation of optical nonlinear materials. It is also shown that this circuit can perform these operations with the inherent parallelism of optics.
