A high performance plasmonic thermal emitter with narrow bandwidth emission property were proposed and fabricated. This emitter is based on a metal coated two-dimensional (2D) photonic crystal of air holes in a silicon substrate. The PC structure is found to be highly effective in suppressing the thermal emission, which can yield 2 orders of magnitude more efficient that conventional IR sources. Thermally...
This work is focused on the design and fabrication of plasmonic nanostructures for spectroscopic applications. Our goal is to fabricate large-surface-area plasmonic nanostructures that provide local enhancement of electromagnetic fields for applications in fluorescence and Raman scattering spectroscopy. Periodic two-dimensional arrays of nanogrooves and nanopillars are obtained by holographic photolithography...
Plasmonic integrated optics is an attempt to bridge the length scale gap between optics and nanometer scale electronic devices. Here we present a hybrid optical interconnect scheme which utilizes low loss dielectric waveguides for global interconnection and plasmonic structures for tightly confining light for local routing and mode manipulation.
Recently, thin-film solar cells enhanced with plasmonic nanoparticles have attracted much attention of the scientific community. To improve the performance of such cells, an optimization of the nanoparticle parameters such as size, surface coverage and material is performed. Based on this optimization, the role of surface plasmons is discussed and analyzed with respect to optical absorption of the...
We propose to use plasmonic modes in a periodic metal-insulator-metal configuration with metallic gratings to enhance emission from silicon nanocrystals. The modification of emission with a change in grating periodicity is experimentally demonstrated.
