2D semiconductors as integrated light sources for plasmonic waveguides
Christian Frydendahl, Torgom Yezekyan, Vladimir Zenin +1
2D materials are compatible with many material platforms as they adhere to other materials strictly by van der Waals interactions. This, together with the variety of band gaps foun…
2D semiconductors as on-chip light sources for integrated nanophotonics
Christian Frydendahl, Torgom Yezekyan, Vladimir A. Zenin +1
Incorporating on-chip light sources directly into nanophotonic waveguides generally requires introducing a different material to the chip than that used for guiding the light, a cr…
Quasi-bound states in the continuum in finite waveguide grating couplers
Torgom Yezekyan, Roza Gabrielyan, Sergey I. Bozhevolnyi
Finite-size effects occurring for quasi-bound states in the continuum (qBIC) formed in symmetric and asymmetric all-dielectric waveguide grating couplers are investigated using num…
Highly efficient, tunable, electro-optic metasurfaces based on quasi-bound states in the continuum
Christopher Damgaard-Carstensen, Torgom Yezekyan, Mark L. Brongersma +1
Ultrafast and highly efficient dynamic optical metasurfaces enabling truly spatiotemporal control over optical radiation are poised to revolutionize modern optics and photonics, bu…
An atlas of photonic and plasmonic materials for cathodoluminescence microscopy
Sven Ebel, Yonas Lebsir, Torgom Yezekyan +2
Cathodoluminescence (CL) microscopy has emerged as a powerful tool for investigating the optical properties of materials at the nanoscale, offering unique insights into the behavio…
Near-field refractometry of van der Waals crystals
Martin Nørgaard, Torgom Yezekyan, Stefan Rolfs +3
Common techniques for measuring refractive indices, such as ellipsometry and goniometry, are ineffective for van der Waals crystal flakes because of their high anisotropy and small…
Inducing room-temperature valley polarization of excitonic emission in transition metal dichalcogenide monolayers
Sergii Morozov, Torgom Yezekyan, Christian Wolff +2
The lowest energy states in transition metal dichalcogenide (TMD) monolayers follow valley selection rules, which have attracted vast interest due to the possibility of encoding an…
Anisotropic Second Harmonic Generation From Monocrystalline Gold Flakes
Sergejs Boroviks, Torgom Yezekyan, Álvaro Rodríguez Echarri +5
Noble metals with well-defined crystallographic orientation constitute an appealing class of materials for controlling light-matter interactions on the nanoscale. Nonlinear optical…
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…
