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...

Plasmon-resonant Nanorods as Multifunctional Imaging Agents
Online Presentations | 28 Dec 2006 | Contributor(s):: Alexander Wei
Gold nanorods have several outstanding characteristics as optical contrastagents for biomedical imaging. Their strong optical absorption atnear-infrared (NIR) frequencies can be used to generate contrast for opticalcoherence tomography (OCT) imaging, and is well matched for detectionmodalities...

Nanoscale Plasmonic Heterostructures
Online Presentations | 15 Dec 2006 | Contributor(s):: Gary P. Wiederrecht
Surface plasmons are electromagnetic modes that are present at the interface of a metal and dielectric material. Depending upon the structure of the metal, surface plasmons demonstrate a wide range of characteristics, such as optical field enhancements, tunable resonances, and the ability to...

Nano Scale Optics with Nearfield Scanning Optical Microscopy (NSOM)
Online Presentations | 16 Nov 2006 | Contributor(s):: Reuben Bakker, Vladimir M. Shalaev
NearfieldScanning Optical Microscopy (NSOM )is a relatively new technology that defeats the diffraction limit for optical measurements by utilizing the near field portion of electromagnetism to window down to ~ 10 nm spatial resolution. NSOM instrumentation has progressively developed over the...
