High-Q localized states in finite arrays of subwavelength resonators
Danil F. Kornovan, Roman S. Savelev, Yuri S. Kivshar +1
We introduce a novel physical mechanism for achieving giant quality factors (-factors) in finite-length periodic arrays of subwavelength optical resonators. The underlying physi…
Topological states in arrays of optical waveguides engineered via mode interference
Roman S. Savelev, Maxim A. Gorlach
Photonic structures with topologically nontrivial bands are usually designed by arranging simple meta-atoms, ideally, single-mode ones, in a carefully designed photonic lattice wit…
Luminescence Enhancement in One-Dimensional Mie-Resonant Arrays
Viktoriia Rutckaia, Frank Heyroth, Georg Schmidt +5
In this paper, we demonstrate the infrared photoluminescence emission from Ge(Si) quantum dots enhanced with collective Mie modes of silicon nanopillars. We show that the excitatio…
Demonstration of the enhanced Purcell factor in all-dielectric structures
Alexander Krasnok, Stanislav Glybovski, Mihail Petrov +5
The Purcell effect is usually described as a modification of the spontaneous decay rate in the presence of a resonator. In plasmonics, this effect is commonly associated with a lar…
Large Purcell enhancement without strong field localization
Alexander Krasnok, Stanislav Glybovski, Mihail Petrov +5
The Purcell effect is defined as the modification of spontaneous decay in the presence of a resonator, and in plasmonics it is usually associated with the large local-field enhance…
Towards all-dielectric metamaterials and nanophotonics
Alexander Krasnok, Sergey Makarov, Mikhail Petrov +3
We review a new, rapidly developing field of all-dielectric nanophotonics which allows to control both magnetic and electric response of structured matter by engineering the Mie re…
