Conquering Surface Plasmon Resonance Loss in Metallic Nanostructures
Online Presentations | 16 Oct 2007 | Contributor(s):: Mikhail A. Noginov
We have observed the compensation of loss in metal by gain indielectric in the mixture of Ag aggregate and rhodamine 6G dye. Thedemonstrated six-fold enhancement of the Rayleigh scattering is the evidence of the enhancement of the localized surface plasmon (SP) resonance. In the attenuated total...

Micro-scaled Biochips with Optically Active Surfaces for Near and Far-field Analysis of Cellular Fluorescence
Online Presentations | 31 Aug 2007 | Contributor(s):: Huw Summers
The integration of thin (< 100 nm) metal films with micro-scaleoptical waveguides provides a route to controlled spatialexcitation of cellular fluorescence within a biochip platform.Surface bound electron-plasma oscillations (surface plasmon waves)interact with photons to produce an evanescent...

Biosensing applications of Plasmon Resonance in gold nanoparticles
Online Presentations | 02 Aug 2007 | Contributor(s):: Karina Moore
Light can be used to excite plasmon resonance in gold nanoparticles. Plasmon resonance occurs on the nanoscale as the particles become excited and plasmon oscillations arise in each particle of a pair of metal nanoparticles. There is plasmon coupling between the neighboring particles as the...

Pulsed Laser Deposition of Thin Films
Online Presentations | 02 Aug 2007 | Contributor(s):: Josh Kaufman
Thin metal films have many applications from optical limiters to nanocircuits. Methods for fabricating these films differ in theory and complexity. Pulsed Laser Deposition (PLD) is a popular method for fabricating thin films. A number of thin films were fabricated using PLD. Silver films of...

Molecular Interferometry
Online Presentations | 26 Jun 2007 | Contributor(s):: David D. Nolte
While single-molecule detection through fluorescence has now become common-place, there has been no analogous single-molecule capability using direct detection approaches such as interferometry. This limitation is slowly yielding to high-speed interferoemtric detection that is pushing the...

Some Remarks to Electrodynamics of Materials with Negative Refraction
Online Presentations | 26 Jun 2007 | Contributor(s):: Victor G. Veselago
The negative refraction coefficient n < 0 can be introduced for isotropic materials with anti-parallel directions of phase and group velocities. If some of material can be described by negative n it will have also negative values of both (electrical ε and magnetic μ) permeabilities. In materials...

Solid-State Lighting: An Opportunity for Nanotechnologists to Address the Energy Challenge
Online Presentations | 25 Apr 2007 | Contributor(s):: Timothy D. Sands
More than one-fifth of the electrical power consumed in the U.S. is used for general illumination. Much of this energy is wasted to heat filaments in incandescent lamps, a century-old technology with an efficiency of about 5%. Fluorescent lighting is more efficient, but problems of color quality,...

Surprises on the nanoscale: Plasmonic waves that travel backward and spin birefringence without magnetic fields
Online Presentations | 08 Jan 2007 | Contributor(s):: Daniel Neuhauser
As nanonphotonics and nanoelectronics are pushed down towards the molecular scale, interesting effects emerge. We discuss how birefringence (different propagation of two polarizations) is manifested and could be useful in the future for two systems: coherent plasmonic transport of near-field...
