Spatial integration and differentiation of optical beams in a slab waveguide by a dielectric ridge supporting high-Q resonances

We show that a very simple structure consisting of a single subwavelength dielectric ridge on the surface of a slab waveguide enables spatial integration and differentiation of the profile of optical beams propagating in the waveguide. The integration and differentiation operations are performed in...
