Metamaterials, as artificially structured materials composed of subwavelength arrays of
resonant unit cells, can exhibit exotic properties beyond those accessible to natural …

BACKGROUND Nanoscale optics is usually associated with plasmonic structures made of
metals such as gold or silver. However, plasmonics suffers from high losses of metals …

Enhancing the light-matter interaction in two-dimensional (2D) materials with high Q
resonances in photonic structures has boosted the development of optical and photonic …

We discuss the recent advances in meta-optics and nanophotonics associated with the
physics of bound states in the continuum (BICs). Such resonant states appear due to a …

The ideal material for nanophotonic applications will have a large refractive index at optical
frequencies, respond to both the electric and magnetic fields of light, support large optical …

Metasurface analogues of electromagnetically induced transparency (EIT) have been a
focus of the nanophotonics field in recent years, due to their ability to produce high-quality …

Metasurfaces without a mirror symmetry may exhibit chiral electromagnetic response that
differs substantially from any type of polarization transformation. A typical design of chiral …

Free from phase-matching constraints, plasmonic metasurfaces have contributed
significantly to the control of optical nonlinearity and enhancement of nonlinear generation …

Metasurfaces have attracted a lot of attention in recent years due to the alternative methods
they provide for the efficient wavefront control and engineering of resonant transmission. We …

We harness non-volatile, amorphous-crystalline transitions in the chalcogenide phase-
change medium germanium antimony telluride (GST) to realize optically-switchable, all …
