Electromagnetic absorbers have drawn increasing attention in many areas. A series of
plasmonic and metamaterial structures can work as efficient narrowband absorbers due to …

The unprecedented ability of nanometallic (that is, plasmonic) structures to concentrate light
into deep-subwavelength volumes has propelled their use in a vast array of nanophotonics …

Resonant plasmonic and metamaterial structures allow for control of fundamental optical
processes such as absorption, emission and refraction at the nanoscale. Considerable …

The detection of photons underpins imaging, spectroscopy, fibre-optic communications and
time-gated distance measurements. Nanostructured materials are attractive for detection …

In gratings, incident light can couple strongly to plasmons propagating through periodically
spaced slits in a metal film, resulting in a strong, resonant absorption whose frequency is …

CMOS compatible electrooptic plasmonic modulators are slated to be key components in
chip-scale photonic circuits. In this work, we investigate detailed design and optimization …

On-chip optical interconnection is considered as a substitute for conventional electrical
interconnects as microelectronic circuitry continues to shrink in size. Central to this effort is …

Surface plasmon photodetectors are of vigorous current interest. Such detectors typically
combine a metallic structure that supports surface plasmons with a photodetection structure …

A compact wavelength demultiplexing structure based on arrayed metal-insulator-metal
(MIM) slot cavities is proposed and demonstrated numerically. The structure consists of a …

A Bragg grating (BG) is a one-dimensional optical device that may reflect a specific
wavelength of light while transmitting all others. It is created by the periodic fluctuation of the …
