Negative Refractivity for Optical Computing

zero_offset writes "This article in EE Times details Purdue's efforts to create a material with negative refractivity. One of the important results would be the ability to create optical computers due to the effect's tendency to amplify and focus light at wavelengths larger than the thickness of the nanowires used in the transmission system. Purdue's School of Electrical and Computer Engineering's Vladimir Shalaev says, "Using these plasmonic nanomaterials, we hope to directly manipulate light, guide it around corners with no losses and basically do all the fundamental operations we do with electronic circuits today, but with photons instead." Nanowires, surface plasmon polaritons, optical computers, nanoscale metamaterials, unnatural refractivity -- what's not to like?" We did a story on the first material known to have a negative index of refraction last year.

      It was hacked. Looks like they have shut down the site now though. You can access a mirror of it here. I'm sure this will be on the news later today.

    After reading Dianetics(by Lron the nut) I came to the
    conclusion that all Scientologists have negative
    refractivity. All you need to do is strap a really
    new CLAM to a gurney and position his or
    her body under the laser of any cd player.
    After 10 minutes under the laser, all of the Body
    Thetans will starting chiming in at a Tone +40.0.
    Hopefully you remembered to put on your goggles because
    the scientologist will start glowing like a lighning
    bugs butt.
    At this point you can start downloading ALL data into
    the Body Thetans of this very willing scientologist. The
    only problem is that the data does not remain stable
    for more than a month. So you will need to repeat
    the procedure every month, unless the CLAM gets
    cleared, in which case ALL of your data will have
    disappeared.
    so it would be in your best interest to keep the young
    budding scienos from CLEARing.
