We present a method to theoretically achieve multispectral ultra-narrowband near-unity
absorption in metal structure with deep-subwavelength plasmonic nanocavities (ie …

During the past decade, a great deal of research work has been carried out on near-field
photonics and nano-optics relating to photo-thermal conversion process. In this paper …

A plasmonic wavelength splitter based on a sub-wavelength metal–insulator–metal (MIM)
periodic rectangle wrinkle waveguide with a graded grating coupler is theoretically analyzed …

Reconfigurable metasurfaces provide a new way for applications requiring dynamic
tunability, such as focusing lenses, holographic displays, optical switch and so on. In this …

The transition from a spectrum filter (resonant transmission) to a polarizer (broadband
transmission) for TM polarized light is observed in a metallic nano-slit array as period is …

High-performance light absorption devices have previously been obtained by coupling
photons to conduction electrons. However, energy harvesting is limited in these devices …

In this paper, we present a free-standing metallodielectric grating structure that can achieve
multiple transmission dips and peaks at normal incidence over the visible spectrum. The …

A new high-performance plasmonic absorber based on the metal-insulator-metal grating
nanostructure is proposed and numerically studied. The effect of geometric parameters of …

We propose a novel structure that can achieve extraordinary optical absorption over the
visible spectrum, based on the guided-mode resonance effect. An optical metal grating with …

Making a continuous metal film with near-unity transparency has received more and more
attention in recent years because of its potential applications for various optoelectronic …
