Optical Device Records in 5-D

Facebook X LinkedIn Email
MELBOURNE, Australia, May 22, 2009 – Optical recording technologies such as DVDs soon could have 2000 times more storage capacity than is currently possible. A new optical device created by Swinburne University of Technology colleagues Peter Zijlstra, Dr. James Chon and professor Min Gu records in five dimensions, thanks to tiny gold rods that form so-called surface plasmons when hit by light. Current discs have three spatial dimensions, but by using nanoparticles, the researchers from the university’s Centre for Micro-Photonics were able to introduce a spectral dimension as well as a polarization dimension, creating...Read full article

    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
