Photonic spin Hall effect mediated by bianisotropy
Dmitry V. Zhirihin, Sergey V. Li, Denis Y. Sokolov +3
Coupling of electric and magnetic responses of a scatterer known as bianisotropy enables rich physics and unique optical phenomena, including asymmetric absorption or reflection, o…
Circular Dichroism Enhancement in Plasmonic Nanorod Metamaterials
D. Vestler, I. Shishkin, E. A. Gurvitz +9
Optical activity is a fundamental phenomenon originating from the chiral nature of crystals and molecules. While intrinsic chiroptical responses of ordinary chiral materials to cir…
Nonlinear symmetry breaking in photo-metamaterials
Maxim A. Gorlach, Dmitry A. Dobrykh, Alexey P. Slobozhanyuk +2
We design and analyze photo-metamaterials with each meta-atom containing both photodiode and light-emitting diode. Illumination of the photodiode by the light-emitting diode gives…
Purcell effect in Hyperbolic Metamaterial Resonators
Alexey P. Slobozhanyuk, Pavel Ginzburg, David A. Powell +8
The radiation dynamics of optical emitters can be manipulated by properly designed material structures providing high local density of photonic states, a phenomenon often referred…
Antenna model of the Purcell effect
Alexander E. Krasnok, Alexey P. Slobozhanyuk, Constantin R. Simovski +5
The Purcell effect - the modification of the spontaneous emission rate in presence of resonant cavities or other resonant objects - is a fundamental effect of quantum electrodynami…
Fano resonances in antennas: General control over radiation patterns
Mikhail V. Rybin, Polina V. Kapitanova, Dmitry S. Filonov +4
The concepts of many optical devices are based on the fundamental physical phenomena such as resonances. One of the commonly used devices is an electromagnetic antenna that convert…
Superdirective dielectric nanoantennas with effect of light steering
Alexander Krasnok, Dmitry Filonov, Alexey Slobozhanyuk +3
We introduce a novel concept of superdirective antennas based on the generation of higher-order optically-induced magnetic multipole modes. All-dielectric nanoantenna can be realiz…
Ultracompact all-dielectric superdirective antennas
Alexander E. Krasnok, Dmitry S. Filonov, Pavel A. Belov +3
We demonstrate a simple way to achieve superdirectivity of electrically small antennas based on a spherical dielectric particle with a notch. We predict this effect theoretically f…
