High-Index Topological Insulator Resonant Nanostructures from Bismuth Selenide
Sukanta Nandi, Shany Z. Cohen, Danveer Singh +4
Topological insulators (TIs) are a class of materials characterized by an insulting bulk and high mobility topologically protected surface states, making them promising candidates…
Temperature Invariant Metasurfaces
Shany Zrihan Cohen, Danveer Singh, Sukanta Nandi +1
Thermal effects are well known to influence the electronic and optical properties of materials through several physical mechanisms and are the basis for various optoelectronic devi…
Deep-subwavelength resonant metaphotonics enabled by high-index topological insulator bismuth telluride
Danveer Singh, Sukanta Nandi, Yafit Fleger +2
In nanophotonics, small mode volumes, high-quality factor (Q) resonances, and large field enhancements without metals, fundamentally scale with the refractive index and are key for…
Amorphous Selenium Mie Resonators for Infrared Meta-Optics
Danveer Singh, Michal Poplinger, Avraham Twitto +9
Applying direct growth and deposition of optical surfaces holds great promise for the advancement of future nanophotonic technologies. Here, we report on a chemical vapor depositio…
Directional out-coupling of light from a plasmonic nanowire-nanoparticle junction
Danveer Singh, Arindam Dasgupta, Aswathy V. G. +2
We experimentally show how a single Ag nanoparticle (NP) coupled to an Ag nanowire (NW) can convert propagating surface plasmon polaritons to directional photons. By employing dual…
