On-chip spatiotemporal optical vortex generation using an integrated metal-dielectric resonator
Artem I. Kashapov, Leonid L. Doskolovich, Evgeni A. Bezus +2
We theoretically demonstrate the possibility of generating a spatiotemporal optical vortex (STOV) beam in a dielectric slab waveguide. The STOV is generated upon reflection of a sp…
Resonant properties of composite structures consisting of several resonant diffraction gratings
Leonid L. Doskolovich, Evgeni A. Bezus, Dmitry A. Bykov +2
We theoretically and numerically investigate resonant optical properties of composite structures consisting of several subwavelength resonant diffraction gratings separated by homo…
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…
