Transient chaos and Rayleigh particle escape out of a time modulated optical trap
E. N. Bulgakov, K. N. Pichugin, D. N. Maksimov
We consider Rayleigh particles in a periodically modulated optical trap formed by two counter-propagating Gaussian beams. It is shown that for certain values of parameters the syst…
Orbital rotation of spheroidal Mie particles driven by counter-propagating circularly-polarized beams
E. N. Bulgakov, A. E. Ershov, V. Kimberg +2
We theoretically consider orbital rotation of a spheroidal submicron particle in the field of two counter-propagating circularly polarized Gaussian beams. We derived equations conn…
Fano resonances induced by symmetry protected bound states in the continuum in dielectric metasurfaces: line-shape prediction by machine learning method
V. S. Gerasimov, A. S. Kostyukov, A. E. Ershov +4
We consider resonances induced by symmetry protected bound states in the continuum in dielectric gratings with in-plane mirror symmetry. It is shown that the shape of the resonance…
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…
