Strain-tunable synthetic gauge fields in topological photonic graphene
Zhen-Ting Huang, Kuo-Bin Hong, Ray-Kuang Lee +4
We propose a straightforward and effective approach to design, by strain-engineering, photonic topological insulators supporting high quality factors edge states. Chiral strain-eng…
TMDC-based topological nanospaser: single and double threshold behavior
Rupesh Ghimire, Fatemeh Nematollahi, Jhih-Sheng Wu +2
We theoretically study a topological nanospaser, which consists of a silver nanospheroid and MoS monolayer ake of a circular shape. The metal nanospheroid acts as a plasmonic n…
Topological Nanospaser
Rupesh Ghimire, Jhih-Sheng Wu, Vadym Apalkov +1
We propose a nanospaser made of an achiral plasmonic-metal nanodisk and a two-dimensional chiral gain medium -- a monolayer transition-metal dichalcogenide (TMDC). When one valley…
Topological Spaser
Jhih-Sheng Wu, Vadym Apalkov, Mark I. Stockman
We theoretically introduce a topological spaser, which consists of a hexagonal array of plasmonic metal nanoshells containing an achiral gain medium in their cores. Such a spaser c…
Fundamentally fastest optical processes at the surface of a topological insulator
S. Azar Oliaei Motlagh, Jhih-Sheng Wu, Vadym Apalkov +1
We predict that a single oscillation of a strong optical pulse can significantly populate the surface conduction band of a three-dimensional topological insulator, Bi2Se3. Both lin…
Electrical detection of hyperbolic phonon-polaritons in heterostructures of graphene and boron nitride
Achim Woessner, Romain Parret, Diana Davydovskaya +11
Light properties in the mid-infrared can be controlled at a deep subwavelength scale using hyperbolic phonons-polaritons (HPPs) of hexagonal boron nitride (h-BN). While propagating…
