Modeling the optical properties of Twisted Bilayer Photonic Crystals
Haoning Tang, Fan Du, Stephen Carr +3
We demonstrate a photonic analog of twisted bilayer graphene that has ultra-flat photonic bands and exhibits extreme slow light behavior. Our twisted bilayer photonic device, which…
Near-Zero Index Photonic Crystals with Directive Bound States in the Continuum
Larissa Vertchenko, Clayton DeVault, Radu Malureanu +2
Near-zero-index platforms arise as a new opportunity for light manipulation with boosting of optical nonlinearities, transmission properties in waveguides and constant phase distri…
Extraordinarily Large Permittivity Modulation in Zinc Oxide for Dynamic Nanophotonics
Soham Saha, Aveek Dutta, Clayton DeVault +7
The dielectric permittivity of a material encapsulates the essential physics of light-matter interaction into the material's local response to optical excitation. Dynamic, photo-in…
Low-loss Zero-Index Materials
Haoning Tang, Clayton DeVault, Phil Camayd-Munoz +7
Materials with a zero refractive index support electromagnetic modes that exhibit stationary phase profiles. While such materials have been realized across the visible and near-inf…
Broad frequency shift of parametric processes in Epsilon-Near-Zero time-varying media
Vincenzo Bruno, Stefano Vezzoli, Clayton DeVault +6
The ultrafast changes of material properties induced by short laser pulses can lead to frequency shift of reflected and transmitted radiation. Recent reports highlight how such a f…
Negative refraction in time-varying, strongly-coupled plasmonic antenna-ENZ systems
V. Bruno, C. DeVault, S. Vezzoli +14
Time-varying metasurfaces are emerging as a powerful instrument for the dynamical control of the electromagnetic properties of a propagating wave. Here we demonstrate an efficient…
