Spatial differentiation and integration of optical beams in a slab waveguide by a single dielectric ridge
Evgeni A. Bezus, Leonid L. Doskolovich, Dmitry A. Bykov +1
We show that a very simple structure consisting of a single subwavelength dielectric ridge on the surface of a slab waveguide enables spatial differentiation and integration of the…

First-order optical spatial differentiator based on a guided-mode resonant grating
Dmitry A. Bykov, Leonid L. Doskolovich, Andrey A. Morozov +4
We present an experimental demonstration of a subwavelength diffraction grating performing first-order differentiation of the transverse profile of an incident optical beam with re…
