Polaritons are hybrid excitations of matter and photons. In recent years, polaritons in van der
Waals nanomaterials—known as van der Waals polaritons—have shown great promise to …

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

Polaritons—hybrid light–matter excitations—enable nanoscale control of light. Particularly
large polariton field confinement and long lifetimes can be found in graphene and materials …

BACKGROUND Light trapped at the nanoscale, deep below the optical wavelength, exhibits
an increase in the associated electric field strength, which results in enhanced light-matter …

Optical frequency combs, which emit pulses of light at discrete, equally spaced frequencies,
are cornerstones of modern-day frequency metrology, precision spectroscopy, astronomical …

Due to its transparent and highly dispersive nature, plasmonically induced transparency
(PIT) has become an attractive field in the on-chip control of light. Conventional methods to …

Abstract 2D optics is gradually emerging as a frontier in modern optics. Plasmons in
graphene provide a prominent platform for 2D optics in which the light is squeezed into …

Due to the two-dimensional character of graphene, the plasmons sustained by this material
have been invariably studied in supported samples so far. The substrate provides stability …

Surface plasmon polaritons (SPPs) can achieve light transmission beyond the diffraction
limit due to their special dispersion relationship. As a novel two-dimensional material …

The integration of two-dimensional (2D) van der Waals materials with nanostructures has
triggered a wide spectrum of optical and optoelectronic applications. Photonic structures of …
