When optical components are reduced to the nanoscale, they exhibit interesting properties that can be harnessed to create new devices. For example, imagine a block of material with thin layers of alternating materials. This creates a periodic arrangement of alternating dielectric constants, forming a "photonic crystal" that is analogous to the electronic crystals used in semiconductor devices. Photonic crystals, along with quantum dots and other devices patterned at the nanoscale, may form the basis for sensors and switches used in computers and telecommunications.

Plasmon-resonant Nanorods as Multifunctional Imaging Agents
out of 5 stars
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...

This submission is an undergraduate project by Raymond Serrano, a chemistry student at UTEP. Raymond has been a nanoHUB student for one year.In addition to being factor of scale, nanoscience is also defined by the changes in the physical and chemical properties the nanoparticles. This...
Nanoscale Plasmonic Heterostructures
15 Dec 2006 |
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)
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...
