Resonant enhancement of Raman scattering in a MoS nanotube
D. R. Kazanov, A. V. Poshakinskiy
The whispering-gallery modes confined in the wall of a multiwall MoS nanotube resonantly enhance the spontaneous Raman scattering by its own optical phonons. The enhancement is…
Direct observation of split-mode exciton-polaritons in a single MoS nanotube
A. I. Galimov, D. R. Kazanov, A. V. Poshakinskiy +5
A single nanotube synthesized from a transition metal dichalcogenide (TMDC) exhibits strong exciton resonances and, in addition, can support optical whispering gallery modes. This…
Twisted Nanotubes of Transition Metal Dichalcogenides with Split Optical Modes for Tunable Radiated Light Resonators
Ilya A. Eliseyev, Bogdan R. Borodin, Dmitrii R. Kazanov +8
Synthesized micro- and nanotubes composed of transition metal dichalcogenides (TMDCs) such as MoS are promising for many applications in nanophotonics, because they combine the…
State-of-the-art and prospects for intense red radiation from core-shell InGaN/GaN nanorods
E. A. Evropeitsev, D. R. Kazanov, Y. Robin +7
Core-shell nanorods (NRs) with InGaN/GaN quantum wells (QWs) are promising for monolithic white light-emitting diodes and multicolor displays. Such applications, however, are still…
Towards exciton-polaritons in MoS nanotubes
D. R. Kazanov, M. V. Rakhlin, K. G. Belyaev +2
We measure low-temperature micro-photoluminescence spectra along a MoS nanotube, which exhibit the peaks of the optical whispering gallery modes below the exciton resonance. Th…
Multiwall nanotubes of molybdenum disulfide as optical resonators
D. R. Kazanov, A. V. Poshakinskiy, V. Yu. Davydov +8
We study the optical properties of MoS nanotubes (NTs) with walls comprising dozens of monolayers. We reveal strong peaks in micro-photoluminescence (-PL) spectra when detec…
Optical activity in chiral stacks of 2D semiconductors
Alexander V. Poshakinskiy, Dmitrii R. Kazanov, Tatiana V. Shubina +1
We show that the stacks of two-dimensional semiconductor crystals with the chiral packing exhibit optical activity and circular dichroism. We develop a microscopic theory of these…
Resonant photonic crystals based on van der Waals heterostructures
D. R. Kazanov, A. V. Poshakinskiy, T. V. Shubina
We propose to use 2D monolayers possessing optical gaps and high exciton oscillator strength as an element of one-dimensional resonant photonic crystals. We demonstrate that such s…
III-nitride tunable cup-cavities supporting quasi whispering gallery modes from ultraviolet to near infrared
T. V. Shubina, G. Pozina, V. N. Jmerik +5
Rapidly developing nanophotonics needs microresonators for different spectral ranges, formed by chip-compatible technologies. In addition, the tunable ones are in greatest demand.…
