A Semi-Classical View on Epsilon-Near-Zero Resonant Tunneling Modes in Metal/Insulator/Metal Nanocavities.

TL;DR: In this paper, a review of recent advances of the theoretical and experimental studies on epsilon-near-zero (ENZ) photonics, especially in the regime of nonlinear ENZ nanophotonics and its applications is presented.

TL;DR: In this paper, a multi-band terahertz superabsorber with a surface structure that consists of a square metallic patch with a very small rectangular hole whose area is only 3.94% of the square patch was presented.

TL;DR: The obtained results clearly show that graphene-based hyperbolic metamaterials with reversibly controlled tunability may be used in the next generation of nonlinear tunable and reversibly switchable devices operating in the mid-IR range.

TL;DR: This work demonstrates the fabrication of high-quality micro- and nanoscale photonic and plasmonic structures via replica molding using pure cellulose and a blended version with nonedible agro-wastes, which are biodegradable in soil and seawater according to the ISO 17556 standard.

TL;DR: This work designs metal/dielectric nanocavities to be resonant with the absorption and emission bands of the employed fluorophores, and discusses the possibility of tailoring the two ENZ wavelengths within the visible spectrum simply by finely designing the thickness of the two dielectric layers, which enables resonance matching with a broad variety of dyes.

TL;DR: In this article, it was shown that a judicious spatial modulation of gain and loss in near zero metamaterials can induce the propagation of exponentially bound interface modes characterized by zero attenuation.

TL;DR: In this paper, the authors compared paraxial light and atom optics and showed that the slowly varying amplitude of a light field in a dielectric medium with a spatially dependent refractive index satisfies an equation which has the form of a Schr\"odinger equation.

TL;DR: In this paper, the Fabry-Perot interferometric principle has been modified to reduce the cavity thickness below the conventional half-wavelength minimum, and the nano-cavities with embedded metasurfaces support independently tunable resonances at multiple bands.
