Nanoscale Antenna Apertures

24 Apr 2007 | Online Presentations | Contributor(s): Xianfan Xu

This presentation will discuss light concentration and enhancement in nanometer-scale ridge aperture antennas. Resent research, including numerical simulations and near field optical measurements has demonstrated that nanoscale ridge antenna apertures can concentrate light into nanometer domain. …

Plasmonic Nanophotonics: Coupling Light to Nanostructure via Plasmons

03 Oct 2005 | Online Presentations | Contributor(s): Vladimir M. Shalaev

The photon is the ultimate unit of information because it packages data in a signal of zero mass and has unmatched speed. The power of light is driving the photonicrevolution, and information technologies, which were formerly entirely electronic, are increasingly enlisting light to communicate and …

Nano Scale Optics with Nearfield Scanning Optical Microscopy (NSOM)

16 Nov 2006 | Online Presentations | 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 …

Some Remarks to Electrodynamics of Materials with Negative Refraction

26 Jun 2007 | Online Presentations | 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 …

Nanotechnology and photonics interview with Phillip Fiorini.

Random Lasers

19 May 2006 | Online Presentations | Contributor(s): Mikhail A. Noginov

Random lasers are the simplest sources of stimulated emission without cavity, with the feedback provided by scattering in a gain medium. First proposed in the late 60’s, random lasers have grown to a large research field. This lecture reviews the state of the art of random lasers, provides …
