Direct imaging of localized surface plasmon polaritons
(Optical Society of America, 2011-08)
In this Letter, we report on dark field imaging of localized surface plasmon polaritons (SPPs) in plasmonic waveguiding bands formed by plasmonic coupled cavities. We image the light scattered from SPPs in the plasmonic ...
Coupled plasmonic cavities on moire surfaces
Surface plasmon polariton (SPP) waveguides formed by coupled plasmonic cavities on metallic Moire surfaces have been investigated both experimentally and numerically. The Moire surface, fabricated by interference lithography, ...
Slowing surface plasmon polaritons on plasmonic coupled cavities by tuning grating grooves
(American Institute of Physics, 2010-09)
We investigate slow surface plasmon polaritons (SPPs) in plasmonic waveguiding bands formed by coupled plasmonic cavities on Moiŕ surfaces. We demonstrate controlling the group velocity and dispersion of the SPPs by varying ...
Localization of surface plasmon polaritons in hexagonal arrays of Moiré cavities
(AIP Publishing, 2011-01)
In view of the progress on the confinement of light, we report on the dispersion characteristics of surface plasmon polaritons (SPPs) on two-dimensional Moire surfaces in the visible part of the electromagnetic spectrum. ...
Pressure sensing using micromachined asymmetric integrated vertical coupler
Analysis of a novel pressure sensor based on a SOI asymmetric vertical coupler is presented. The integrated optical component is a coupler composed of a single mode low index waveguide and a thin silicon slab.
Atomic layer deposited Al 2O 3 passivation of type II InAs/GaSb superlattice photodetectors
Taking advantage of the favorable Gibbs free energies, atomic layer deposited (ALD) aluminum oxide (Al 2O 3) was used as a novel approach for passivation of type II InAs/GaSb superlattice (SL) midwave infrared (MWIR) single ...
Passivation of type II InAs / GaSb superlattice photodetectors with atomic layer deposited Al2O3
We have achieved significant improvement in the electrical performance of the InAs/GaSb midwave infrared photodetector (MWIR) by using atomic layer deposited (ALD) aluminium oxide (Al2O3) as a passivation layer. Plasma free ...
Slow plasmons in grating cavities
Recent research on surface plasmon polaritons and their applications have brought forward a wealth of information and continues to be of interest to many. In this report, we concentrate on propagating surface plasmon ...
Novel integrated optical displacement sensor for scanning force microscopies
A novel displacement sensor for scanning force microscoples using an integrated optical micro-ring resonator is described. Device operates by monitoring the changes in transmission spectrum of micro-ring resonator. This ...
