Electrically driven reprogrammable vanadium dioxide metasurface using binary control for broadband beam-steering
Matthieu Proffit, Sara Peliviani, Pascal Landais +1
Resonant optical phased arrays are a promising way to reach fully reconfigurable metasurfaces in the optical and NIR regimes with low energy consumption, low footprint and high rel…
Polaritonic Critical Coupling in a Hybrid Quasi-Bound States in the Continuum Cavity-WS Monolayer System
Xia Zhang, A. Louise Bradley
We theoretically propose and numerically demonstrate that perfect feeding of a polaritonic system with full electromagnetic energy under one-port beam incidence, referred to as pol…
Absorbance Enhancement of Monolayer MoS in a Perfect Absorbing System
Xia Zhang, Julia Lawless, Jing Li +4
We reveal numerically and experimentally that dielectric resonance can enhance the absorbance and emission of monolayer MoS. By quantifying the absorbance of the Si disk resona…
Ultra-Spatiotemporal Light Confinement in Dielectric Nanocavity Metasurfaces
Xia Zhang, A. Louise Bradley
Light concentration with strong temporal and spatial confinement is crucial for tailoring light-matter interaction. Electromagnetic cavity modes in photonic and plasmonic resonator…
Wide-Angle Invisible Dielectric Metasurface Driven by Transverse Kerker Scattering
