Efficient nonlinear optical interactions are essential for many applications in modern
photonics. However, they typically require intense laser sources and long interaction …

Structures with near-zero parameters (for example, media with near-zero relative permittivity
and/or relative permeability, and thus a near-zero refractive index) exhibit a number of …

The discovery, design and development of materials are critically linked to advances in
many areas of research, and optics is no exception. Recently, the spectral region in which …

Metamaterials with a Dirac-like cone dispersion at the center of the Brillouin zone behave
like an isotropic and impedance-matched zero refractive index material at the Dirac-point …

Abstract Epsilon‐near‐zero (ENZ) photonics is the study of light–matter interactions in the
presence of structures with near‐zero permittivity and has been emerging as an important …

A zero-refractive-index metamaterial is one in which waves do not experience any spatial
phase change, and such a peculiar material has many interesting wave-manipulating …

Transparent conducting oxides have recently gained great attention as CMOS-compatible
materials for applications in nanophotonics due to their low optical loss, metal-like behavior …

The invisibility cloak, a long-standing fantastic dream for humans, has become more
tangible with the development of metamaterials. Recently, metasurface-based invisibility …

Balancing complexity and simplicity has played an important role in the development of
many fields in science and engineering. One of the well-known and powerful examples of …

Doping a semiconductor with foreign atoms enables the control of its electrical and optical
properties. We transplant the concept of doping to macroscopic photonics, demonstrating …
