Plasmonic excitations, consisting of collective oscillations of the electron gas in a conductive
film or nanostructure coupled to electromagnetic fields, play a prominent role in photonics …

In the past decade, the realisation of negative index materials has initiated extensive
research into metamaterials. Perfect absorbers and reflectors are of particular interest as …

We study spectral singularities and critical field enhancement factors associated with
embedded photonic bound states in subwavelength periodic Si films. Ultrahigh-Q …

A metamaterial perfect absorber composed of a black phosphorus (BP) monolayer, a
photonic crystal, and a metallic mirror is designed and investigated to enhance light …

Perfect absorption (PA) of incident light is important for both fundamental light-matter
interaction studies and practical device applications. PA studies so far have mainly used …

Liquid-crystal devices are a promising cheap alternative for terahertz light modulation, albeit
they suffer from problems associated with thick cells. Here we describe a few-micron-thick …

Resonant dielectric metasurfaces have been demonstrated to hold a great promise for
manipulation of light-wave dispersion at the nanoscale due to their resonant photonic …

Optical switches based on dielectric nanostructures are highly desired at present. To
enhance the wavelength-selective light absorption, and achieve an absorption-induced …

Lamellar gratings are investigated via temporal coupled-mode theory and numerical
simulations. Total absorption can be achieved by an optimized grating with shallow grooves …

The combination of efficient single-photon generation, manipulation, and detection on a
single chip poses a major challenge for quantum photonics and all-optical quantum …
