How many parameters do we need to obtain a BIC in symmetric and asymmetric structures?
Dmitry A. Bykov, Evgeni A. Bezus, Albert A. Mingazov +1
Photonic bound states in the continuum (BICs) are nonradiating eigenmodes of structures with open scattering channels. Most often, BICs are studied in highly symmetric structures w…
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…
One-dimensional quasi bound states in the continuum in the ω~k space for nonlinear optical applications
Kaili Sun, Hui Jiang, Dmitry A. Bykov +4
The phenomenon of bound state in the continuum (BIC) with infinite quality factor and lifetime has emerged in recent years in photonics as a new tool of manipulating light-matter i…
Analytical design of flat-top transmission filters composed of several resonant structures
Leonid L. Doskolovich, Nikita V. Golovastikov, Dmitry A. Bykov +1
Resonant properties of composite structures consisting of several identical resonant diffractive structures (e.g. multilayer thin-film structures or guided-mode resonance gratings)…
Coupled-wave formalism for bound states in the continuum in guided-mode resonant gratings
Dmitry A. Bykov, Evgeni A. Bezus, Leonid L. Doskolovich
We present simple yet extremely accurate coupled-wave models describing the formation of bound states in the continuum (BICs) in 1D-periodic guided-mode resonant gratings (GMRGs) c…
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…
