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…
Reflectivity-based refractive index measurement of van der Waals materials
Xavier Zambrana-Puyalto, Alexander Johan Olsen, Søren Raza
We present a reflectivity-based method for measuring the in-plane refractive index of transparent van der Waals (vdW) materials. The approach enables the characterization of as sma…
Experimental demonstration of a beam shaping non-imaging metasurface
Kirstine Engell Sandager Poulsen, Xavier Zambrana-Puyalto, Rafael de la Fuente Herrezuelo +2
Light emitting diodes have superior performance over most other light sources, but the need for secondary optics to shape their illumination for specific applications yield bulky l…
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…
Quality factor of dielectric optical resonators
Xavier Zambrana-Puyalto, Søren Raza
We show analytically that the quality () factor of magnetic and electric Mie modes in a lossless dielectric spherical resonator with high refractive index () scales as…
