Thermo-optic bistability in 2D all-dielectric resonators
G. V. Shadrina, D. N. Maksimov, E. N. Bulgakov
We consider thermo-optic bistability in resonant excitation of high-quality modes in two-dimensional dielectric resonators. We develop a coupled-mode theory approach which account…

Optical chromatography ultra small particles by Brownian motion in tilted optical potential induced by bound states in the continuum
Evgeny N. Bulgakov, Galina V. Shadrina
We investigate sorting Rayleigh optical particles up to several nanometers in size during Brownian motion in an tilted periodic potential with multiple deep wells. The wells are in…

Super bound states in the continuum through merging in grating
Evgeny Bulgakov, Galina Shadrina, Almas Sadreev +1
Bound states in the continuum (BICs) in gratings composed of infinitely long silicon rods of rectangular cross-section are considered. We reveal merging off- Friedrich-Wintgen B…
