TL;DR: In this paper, an integrated on-chip integrated metamaterial with a refractive index of zero in the optical regime is presented, where light refracts perpendicular to the facets of a prism made of this metammaterial, directly demonstrating that the index of refraction is zero.

TL;DR: Recently, a new class of materials with a vanishing permittivity, known as epsilon-near-zero (ENZ) materials, has been reported to exhibit unprecedented ultrafast nonlinear efficiencies within sub-wavelength propagation lengths as discussed by the authors.

TL;DR: A plasmonic metasurface with a quality-factor (Q-factor) of 2340 in the telecommunication C band by exploiting surface lattice resonances (SLRs) was reported in this article.

TL;DR: The authors present an experimental demonstration of adiabatic frequency conversion using the concept of time boundary by exploiting the properties of an ITO film operating near its epsilon-near-zero frequency.

TL;DR: Amorphous and polycrystalline anatase TiO(2) thin films and submicrometer-wide waveguides with promising optical properties for microphotonic devices are demonstrated and transmission of 780-nm light through microbends having radii down to 2 μm and variable signal splitting in microphotonics couplers are shown.
