Description
Summary:The authors consider the 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. Numerical simulation results show the investigated structures allow the spatial differentiation operation to be performed with high quality. The presented results could find application in new systems for optical information processing and analog optical computing based on integrated nanophotonic structures.
