Thermo-optical bistability enabled by bound states in the continuum in silicon metasurfaces
Alexander Barulin, Olesia Pashina, Daniil Riabov +9
The control of light through all-optical means is a fundamental challenge in nanophotonics and a key effect in optical switching and logic. The optical bistability effect enables t…
Numerical simulation of the electromagnetic wave reflection from 2D random semi-infinite strongly scattering media
Sofia Ponomareva, Alexey A. Shcherbakov
Light scattering in disordered media plays an important role in various areas of applied science from biophysics to astronomy. In this paper we study two approaches to calculate sc…
Generation of nearly pure and highly directional magnetic light in fluorescence of rare earth ions
Anton D. Utyushev, Roman Gaponenko, Song Sun +3
A thorough analysis of the emission via the magnetic dipole (MD) transition, called magnetic light below, of trivalent rare-earth ions in or near dielectric homogeneous spheres has…
Experimental demonstration of superdirective spherical dielectric antenna
Roman Gaponenko, Mikhail S. Sidorenko, Dmitry Zhirihin +5
An experimental demonstration of directivities exceeding the fundamental Kildal limit, a phenomenon called superdirectivity, is provided for spherical high-index dielectric antenna…
Bound states in the continuum in photonic structures
Kirill Koshelev, Zarina Sadrieva, Alexey Shcherbakov +2
Bound states in the continuum provide a remarkable example of how a simple problem solved about a century ago in quantum mechanics can drive the research on a whole spectrum of res…
Reformulated Fourier Modal Method with improved near field computations
Sergey Spiridonov, Alexey A. Shcherbakov
In this paper we propose a new formulation of the Fourier Modal Method based on an alternative treatment of interface conditions allowing us to overcome the effect of the Gibbs phe…
