A series of avoided crossings of resonances in the system of several different dielectric resonators results in giant Q-factors

Konstantin Pichugin, Almas Sadreev, Evgeny Bulgakov

We perform optimization of Q-factor in the system of freestanding three/four/five/six coaxial subwavelength dielectric disks over all scales. Each parameter contributes almost one…

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…

Super quasi-bound state in the continuum

Zhanyuan Zhang, Evgeny Bulgakov, Konstantin Pichugin +3

Avoided crossing of resonances and merging multiple bound states in the continuum (BICs) are parallel means for tailoring the physical properties of BICs. Herein, we introduce a ne…

Thermo-optic hysteresis with bound states in the continuum

D. N. Maksimov, A. S. Kostyukov, A. E. Ershov +3

We consider thermo-optic hysteresis in a silicon structure supporting bound state in the continuum. Taking into account radiative heat transfer as a major cooling mechanism we cons…

Desktop laboratory of bound states in the continuum in metallic waveguide with dielectric cavities

Evgeny Bulgakov, Artem Pilipchuk, Almas Sadreev

We consider dielectric cavities whose radiation space is restricted by two parallel metallic planes. The TM solutions of the Maxwell equations of the system are equivalent to the s…

Degenerate bound states in the continuum in square and triangular open acoustic resonators

Almas Sadreev, Evgeny Bulgakov, Artem Pilipchuk +2

We consider square and equilateral triangular open acoustic resonators with the and symmetries, respectively. There is an unique property of square and triangular…
