Broadband tunable mid-infrared absorber based on conductive strip-like meta-atom elements
Henrik Parsamyan, Hovhannes Haroyan, Khachatur Nerkararyan
A metamaterial composed of thin metallic strips as an efficient broadband absorber in the mid-infrared spectrum is investigated. Here the matching between dielectric and geometrica…
Analysis of bistability at the coupling between waveguide and whispering gallery modes of a nonlinear hemicylinder
Henrik Parsamyan, Khachik Sahakyan, Khachatur Nerkararyan
The optical bistability caused by the coupling between modes of the parallel-plate waveguide and a nonlinear hemicylindrical crystal is studied using theoretical and numerical anal…
Light control in a hemicylindrical whispering gallery microcavity-parallel plate waveguide system
Henrik Parsamyan, Hovhannes Haroyan, Khachatur Nerkararyan
We have shown that a structure composed of a semiconductor hemicylinder and a dielectric waveguide separated by a thin metal layer permits efficient and easy light control. In such…
Semicylindrical microresonator: excitation, modal structure, and Q factor
Hovhannes Haroyan, Henrik Parsamyan, Torgom Yezekyan +1
The semicylindrical microresonator with relatively simple excitation with a plane wave is studied. The resonator is formed on the base of the dielectric/metal/dielectric structure,…
Efficient broadband infrared absorbers based on core-shell nanostructures
Henrik A. Parsamyan, Khachatur V. Nerkararyan, Sergey I. Bozhevolnyi
We suggest to exploit dielectric-metal core-shell nanostructures for efficient resonant and yet broadband absorption of infrared radiation with deeply subwavelength configurations.…
Dynamics of a quantum emitter resonantly coupled to both external field and localized surface plasmon
Khachatur V. Nerkararyan, Torgom S. Yezekyan, Sergey I. Bozhevolnyi
We investigate excitation dynamics in the system of a quantum dipole emitter (QDE) coupled to a located nearby metal nanoparticle (MNP), which exhibits a dipolar localized surface…
Enhanced non-resonant light transmission through subwavelength slits in metal
Anders Pors, Khachatur V. Nerkararyan, Khachik Sahakyan +1
We analytically describe light transmission through a single subwavelength slit in a thin perfect electric conductor screen for the incident polarization being perpendicular to the…
Entanglement of two qubits mediated by a localized surface plasmon
Khachatur V. Nerkararyan, Sergey I. Bozhevolnyi
We investigate relaxation dynamics in the system of two identical quantum dipole emitters (QDEs) located near a metal nanoparticle (MNP) exhibiting a dipolar localized surface plas…
Scaling in light scattering by sharp conical metal tips
Anders Pors, Khachatur V. Nerkararyan, Sergey I. Bozhevolnyi
Using the electrostatic approximation, we analyze electromagnetic fields scattered by sharp conical metal tips, which are illuminated with light polarized along the tip axis. We es…
Relaxation of a Quantum Emitter Resonantly Coupled to a Metal Nanoparticle
Khachatur V. Nerkararyan, Sergey I. Bozhevolnyi
Presence of a metal nanoparticle near a quantum dipole emitter, when a localized surface plasmon mode is excited via the resonant coupling with an excited quantum dipole, changes d…
