Enhanced and directional light emission from two-dimensional excitons using Mie voids
Avishek Sarbajna, Ganesh Ghimire, Ilia Breev +5
Controlling light emission at the nanoscale has important applications in solid-state lighting, displays, and quantum light sources. Achieving this control requires both enhanced l…
Apparent Resonance Splitting in Self-Coupled Excitonic Systems
Avishek Sarbajna, Qitong Li, Dorte Rubæk Danielsen +6
Thin films of high-refractive-index excitonic materials enable self-coupling by simultaneously supporting intrinsic excitonic transitions and optical resonances. These optical reso…
Computational discovery of high-refractive-index van der Waals materials: The case of HfS
Xavier Zambrana-Puyalto, Mark Kamper Svendsen, Amalie H. Søndersted +9
New high-refractive-index dielectric materials may enhance many optical technologies by enabling efficient manipulation of light in waveguides, metasurfaces, and nanoscale resonato…
Fourier-Tailored Light-Matter Coupling in van der Waals Heterostructures
Dorte R. Danielsen, Nolan Lassaline, Sander J. Linde +7
Dielectric structures can support low-absorption optical modes, which are attractive for engineering light-matter interactions with excitonic resonances in two-dimensional (2D) mat…
Encapsulated void resonators in lossy dielectric van der Waals heterostructures
Avishek Sarbajna, Dorte Rubæk Danielsen, Laura Nevenka Casses +3
Dielectric optical resonators traditionally rely on materials with the combination of high refractive indices and low optical losses. Such materials are scarce for operation in vis…
