A plasmonic splitter based on slot cavity is proposed and numerically investigated using
finite-difference-time-domain (FDTD) methods. The structure consists of the input …

A multichannel metallic dual nano-wall square split-ring resonator is proposed for both filter
and sensor applications. It is comprised of four square split-ring resonators which filter out …

We have proposed a graded grating plasmonic system with a significant slow-light effect for
the propagation of high-confinement surface plasmon (SP) wave. Theoretical analysis and …

Vertical plasmonic Mach-Zehnder Interferometers are investigated theoretically and
experimentally, and their potential for ultra-sensitive optical sensing is discussed. Plasmonic …

We have proposed and numerically investigated an all-optical switch based on a metal–
insulator–metal waveguide with graded nonlinear plasmonic gratings. The influences of …

In this paper, we numerically study both band-pass and band-stop plasmonic filters based
on Metal-Insulator-Metal (MIM) waveguides and circular ring resonators. The band-pass …

A 3-D vertical hybrid plasmonic switch having vanadium oxide (VO 2) Bragg grating element

We experimentally demonstrate a metal–film bidirectional surface wave splitter for guiding
light at two visible wavelengths in opposite directions. Two nanoscale gratings were …

Bidirectional surface wave splitters excited by a cylindrical wire in the microwave frequency
have been proposed and fabricated. Compared to the bidirectional subwavelength-slit …
