Here we use epsilon-near-zero nanocavities filled with a model polar medium (SiO2) to demonstrate ultrastrong coupling between phonons and gap plasmons. We present classical and quantum-mechanical models to quantitatively describe the observed plasmon–phonon ultrastrong coupling phenomena and demonstrate ...

Here we propose and numerically demonstrate a robust on-chip quantum network based on an epsilon-near-zero (ENZ) material, whose dielectric function has the real part close to zero. We show that ENZ materials strongly protect quantum information against decoherence and losses during its propagation...
While, integration with epsilon-near-zero (ENZ) materials can enhance the refractive index contrast to infinity, leading to phenomena such as resonance nesting and mode degeneracy of monolayer or bilayer spherical dielectric cavities within ENZ materials [25], [26]. ENZ materials, a subtype of ...
Epsilon-near-zero(ENZ)介质是一个新兴的平台,具有新颖的纳米光子现象的巨大潜力。获得ENZ介质的一种方法是在等离激元波导的基本模式的截止波长下工作。对这种模式的控制仅限于波导的材料和尺寸属性。在这里,我们证明等离激元纳米结构(nanorod)可以牢固地耦合到等离激元波导,提供两个新的混合共振模式,展现出引导的ENZ...

We theoretically demonstrate that at certain frequencies two-dimensional dielectric photonic crystals(PCs)may be regarded as either epsilon-near-zero or mu-near-zero materials.We show that the transmission through a slab of such materials upon normal incidence is normally non-unity and decays with sl...
Recently, epsilon-near-zero (ENZ) materials have been employed to stimulate light funnelling enhancement through a subwavelength metallic channel. In this paper, we present a study of enhanced optical transmission through subwavelength metallic gratings deposited on ENZ material and gallium-arsenide (GaAs...
Nonlinear opticsMaterials with vanishingly small dielectric permittivity, known as epsilon-near-zero materials, enable strong ultrafast optical nonlinear responses within a sub-wavelength propagation length. This Review surveys the various observations of nonlinear phenomena in this class of materials....
