Towards on-chip nascent all-van-der-Waals polarization optical components for nanoscale photonic applications
Dmitrii Litvinov, Ilia Begichev, Iakov Reznikov +8
The integration of polarization-control elements into nanoscale photonic circuits remains a central challenge for modern on-chip optical technologies, which call for continuous min…
Probing the temperature dependence of dielectric function of ternary transition metal dichalcogenides: towards thermo-driven ultrathin photonic components
Artsruni Margaryan, Maria Levonyan, Maksim Sargsyan +4
Transition metal dichalcogenides (TMDs), along with their ternary derivatives, have attracted considerable attention mostly due to pronounced excitonic resonances emerging in visib…
Broadband dielectric permittivity tensor of muscovite for next-generation all van der Waals photonic components
Meri Hayrapetyan, Maksim Sargsyan, David Karakhanyan +8
We report a comprehensive determination of the broadband dielectric permittivity tensor of van der Waals (vdW) muscovite also referred to as mica, establishing it as a low-index lo…
Dielectric permittivity tensor dynamics of in-plane hyperbolic van der Waals MoOCl2 and emergent chiral photonic applications
Artsruni Margaryan, Maksim Sargsyan, Meri Hayrapetyan +3
Van der Waals (vdW) crystals offer unique opportunities for modern nanophotonic applications owing to their intrinsic anisotropic nature. While most of them exhibit uniaxial anisot…
Record Index-Bandgap Trade-off: CdPS3 as a High-Index van der Waals Platform for Ultraviolet-Visible Nanophotonics
M. R. Povolotskiy, A. S. Slavich, G. A. Ermolaev +21
The development of nanophotonics is hindered by a fundamental trade-off between a material's refractive index (n) and its electronic bandgap (Eg), which severely restricts the choi…
L-Cysteine Polymorph Coatings for THz Sensing Metasurfaces
M. Zhezhu, A. Vasilev, H. Parsamyan +5
The electromagnetic response of metasurfaces can be intentionally engineered by carefully designing their unit cells. Narrowband metasurfaces, characterized by high quality factors…
