Spontaneous emission enhancement in metal-dielectric metamaterials
Ivan Iorsh, Alexander Poddubny, Alexey Orlov +2
We study the spontaneous emission of a dipole emitter imbedded into a layered metal-dielectric metamaterial. We demonstrate ultra-high values of the Purcell factor in such structur…
An arrayed nanoantenna for broadband light emission and detection
Andrey. E. Miroshnichenko, Ivan S. Maksymov, Arthur R. Davoyan +3
We suggest a broadband optical unidirectional arrayed nanoantenna consisting of equally spaced nanorods of gradually varying length. Each nanorod can be driven by near-field quantu…
Spontaneous radiation of a finite-size dipole emitter in hyperbolic media
Alexander N. Poddubny, Pavel A. Belov, Yuri S. Kivshar
We study the radiative decay rate and Purcell effect for a finite-size dipole emitter placed in a homogeneous uniaxial medium. We demonstrate that the radiative rate is strongly en…
Engineered Optical Nonlocality in Nanostructured Metamaterials
Alexey A. Orlov, Pavel M. Voroshilov, Pavel A. Belov +1
We analyze dispersion properties of metal-dielectric nanostructured metamaterials. We demonstrate that, in a sharp contrast to the results for the corresponding effective medium, t…
