2D Plasmonics for Enabling Novel Light-Matter Interactions
Nicholas Rivera, Ido Kaminer, Bo Zhen +2
The physics of light-matter interactions is strongly constrained by both the small value of the fine-structure constant and the small size of the atom. Overcoming these limitations…
Substrate-Independent Light Confinement in Bioinspired All-Dielectric Surface Resonators
Emma C. Regan, Yichen Shen, Josue J. Lopez +4
Traditionally, photonic crystal slabs can support resonances that are strongly confined to the slab but also couple to external radiation. However, when a photonic crystal slab is…
Controlling Directionality and Dimensionality of Wave Propagation through Separable Bound States in the Continuum
Nicholas Rivera, Chia Wei Hsu, Bo Zhen +3
A bound state in the continuum (BIC) is an unusual localized state that is embedded in a continuum of extended states. Here, we present the general condition for BICs to arise from…
Spawning rings of exceptional points out of Dirac cones
Bo Zhen, Chia Wei Hsu, Yuichi Igarashi +6
The Dirac cone underlies many unique electronic properties of graphene and topological insulators, and its band structure--two conical bands touching at a single point--has also be…
