Reverse resonant nonspecular reflection controlled by intensity of light
Sergiy Prosvirnin, Vyacheslav Khardikov, Vladimir Yachin +2
Nonlinear optical features of a plane structure consisted of silicon disks placed periodically on a silver substrate have been studied in the Littrow reflection scenario. The struc…
Resonant response in tunable metasurface based on crossed all-dielectric gratings
Vladimir V Yachin, Vyacheslav V Khardikov, Ludmila A Kochetova +3
We theoretically demonstrate mechanical tuning of the spectral response of a Mie-like resonant dielectric metasurface consisting of crossed all-dielectric strip gratings. We use tw…
Non-specular reflection by a planar resonant metasurface
Sergey L Prosvirnin, Vyacheslav V Khardikov, Kateryna L Domina +3
An uncommon double-ray scenario of light resonant scattering by a periodic metasurface is proposed to provide strong non-specular reflection. The metasurface is constracted as an a…
Optical Magnetic Lens: towards actively tunable terahertz optics
Georgii Shamuilov, Katerina Domina, Vyacheslav Khardikov +2
As we read this text, our eyes dynamically adjust the focal length to keep the line image in focus on the retina. Similarly, in many optics applications the focal length must be dy…
Bonding and antibonding modes in metal-dielectric-metal plasmonic antennas for dual-band applications
Kateryna L. Domina, Vyacheslav V. Khardikov, Vitaliy Goryashko +1
Resonant optical antennas supporting plasmon polaritons (SPPs) - collective excitations of electrons coupled to electromagnetic fields in a medium - are relevant to sensing, photov…
Homogeneous enhancement of electric near-field in all-dielectric metasurfaces composed of cluster-based unit cells
Anton S. Kupriianov, Kateryna L. Domina, Vyacheslav V. Khardikov +2
In order to construct a dielectric analog of spaser, we study theoretically and experimentally several configurations of cluster-based unit cells for an all-dielectric metasurface…
Controlling high-Q trapped modes in polarization-insensitive all-dielectric metasurfaces
Andrey Sayanskiy, Anton S. Kupriianov, Su Xu +4
We reveal peculiarities of the trapped (dark) mode excitation in a polarization-insensitive all-dielectric metasurface, whose unit super-cell is constructed by particularly arrangi…
All-dielectric resonant metasurfaces with a strong toroidal response
Vladimir R. Tuz, Vyacheslav V. Khardikov, Yuri S. Kivshar
We demonstrate how to create all-dielectric metasurfaces with a strong toroidal response by arranging two types of nanodisks into asymmetric quadrumer clusters. We demonstrate that…
High-quality trapped modes in all-dielectric metamaterials
Vladimir R. Tuz, Vyacheslav V. Khardikov, Anton S. Kupriianov +4
A planar all-dielectric metamaterial made of a double-periodic lattice whose unit cell consists of a single subwavelength dielectric particle having the form of a disk possessing a…
Enhancement of quantum dot luminescence in all-dielectric metamaterial
Vyacheslav V. Khardikov, Sergey L. Prosvirnin
We propose a simple design of all-dielectric silicon-based planar metamaterial manifested an extremely sharp resonant reflection and transmission in the wavelength of about 1550 nm…
Giant red shift and enhancement of resonant light confinement in planar array of dielectric bars
Vyacheslav Khardikov, Ekaterina Iarko, Sergey Prosvirnin
Results of research of resonant phenomena in planar periodic structures consisted of dielectric elements are presented. A problem of plane wave diffraction by a structure which a p…
