Modern nanotechnology allows one to scale down various important devices (sensors,
chips, fibers, etc.) and thus opens up new horizons for their applications. The efficiency of …

This review provides a perspective on the recent developments in the transmission of light
through subwavelength apertures in metal films. The main focus is on the phenomenon of …

This Colloquium analyzes the interaction of light with two-dimensional periodic arrays of
particles and holes. The enhanced optical transmission observed in the latter and the …

Metasurface-based structural coloration is a promising enabling technology for advanced
optical encryption with a high-security level. Herein, we propose a paradigm of electrically …

Fluorescence spectroscopy is widely used in biological research. Until recently, essentially
all fluorescence experiments were performed using optical energy which has radiated to the …

Plasmonic-based chemical sensing technologies play a key role in chemical, biochemical,
and biomedical research, but basic research in this area is still attracting interest …

Optical metasurfaces made of 2D nanoantenna arrays are emerging with extraordinary
abilities in controlling the flow of light at subwavelength length scales.[21, 22] It has been …

By using the rigid full-vectorial three-dimensional finite-difference time-domain method, we
show that the enhanced transmission through a metallic film with a periodic array of …

Dielectric and metallic gratings have been studied for more than a century. Nevertheless,
novel optical phenomena and fabrication techniques have emerged recently and have …

Abstract Point-of-care (POC) applications have expanded hugely in recent years and is
likely to continue, with an aim to deliver cheap, portable, and reliable devices to meet the …
