Abstract
We consider optical properties of integrated metal-dielectric-metal structures embedded in a dielectric slab waveguide and their application to the problems of first- and second-order optical differentiation of the profile of the incident optical beam in reflection. According to the presented numerical simulation results, the investigated structures enable performing the spatial differentiation operation with high quality. The presented results may find application in novel systems for optical information processing and analog optical computing based on integrated nanophotonic structures.
