Abstract
We propose the implementation of an optical multiwavelength full adder. Several optical wavelengths are used to encode the bits of the binary numbers to be added so that the broad spectral bandwidth of optical systems can be utilized. We demonstrate the carry generation for the proposed optical multiwavelength full adder, using a novel scheme of four-wave mixing in photorefractive crystals.Keywords
