Bound states in the continuum and high-Q resonances supported by a dielectric ridge on a slab waveguide
Evgeni A. Bezus, Dmitry A. Bykov, Leonid L. Doskolovich
We investigate the diffraction of guided modes of a dielectric slab waveguide on a simple integrated structure consisting of a single dielectric ridge on the surface of the wavegui…
Designing double freeform surfaces for collimated beam shaping with optimal mass transportation and linear assignment problems
Leonid L. Doskolovich, Dmitry A. Bykov, Evgeniy S. Andreev +2
We propose a method for designing refractive optical elements for collimated beam shaping. In this method, the problem of finding a ray mapping is formulated as a linear assignment…
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…
