Revealing Low-Radiative Modes of Nanoresonators with Internal Raman Scattering
K. V. Baryshnikova, K. Frizyuk, G. Zograf +7
Revealing hidden non-radiative (dark) of resonant nanostructures using optical methods such as dark-field spectroscopy often becomes a sophisticated problem due to a weak coupling…
Different regimes of Purcell Effect in Disordered Photonic Crystals
K. M. Morozov, A. R. Gubaydullin, K. A. Ivanov +2
We demonstrate that disorder in photonic crystals could lead to pronounced modification of spontaneous emission rate in the frequency region corresponding to the photonic band gap…
Enhancement of inherent Raman scattering in dielectric nanostructures with electric and magnetic Mie resonances
Kristina Frizyuk, Mehedi Hasan, Alex Krasnok +2
Resonantly enhanced Raman scattering in dielectric nanostructures has been recently proven to be an effcient tool for developing nanothermometry and experimental determination of t…
Dielectric nanoantenna as an efficient and ultracompact demultiplexer for surface waves
Ivan S. Sinev, Andrey A. Bogdanov, Filipp E. Komissarenko +7
Nanoantennas for highly efficient excitation and manipulation of surface waves at nanoscale are key elements of compact photonic circuits. However, previously implemented designs e…
Collective polaritonic modes in an array of two-level quantum emitters coupled to optical nanofiber
D. F. Kornovan, A. S. Sheremet, M. I. Petrov
In this paper we develop a microscopic analysis of the light scattering on a periodic two-level atomic array coupled to an optical nanofiber. We extend the scattering matrix approa…
Resonant Raman Scattering from Silicon Nanoparticles Enhanced by Magnetic Response
Pavel A. Dmitriev, Denis G. Baranov, Valentin A. Milichko +6
Enhancement of optical response with high-index dielectric nanoparticles is attributed to the excitation of their Mie-type magnetic and electric resonances. Here we study Raman sca…
