Light Resonators Used To Move Nano-Sized Objects

Posted by timothy on from the tiny-stuff dept.

ElectricSteve writes "Scientists at Cornell University report they can now use a light beam carrying a single milliwatt of power to move objects and even change the optical properties of silicon from opaque to transparent at the nanometric scale." As the article says, such an advancement "could prove very useful for the future of micro-electromechanical (MEMS) and micro-optomechanical (MOMS) systems."

  4. Future switching? by sander · · Score: 4, Interesting

    I wonder if this will be used in future optical routers and switches or even processors - if the opaque-transparent (and back) switch happens fast enough, you could easily do a very large number of parallel on-off switches to optical pathways. No need for lots of MEMS/MOMS mirrors any more.

    Imagine a nanoscale thinking machines cm-5, except the light panels would then actually be part of the computation, controlling which nodes are on or off.

      It's an acronym. It has no meaning, it's just an abbreviation of Micro-OptoMechanical Systems. Perhaps you were waiting for someone to make a totally contrived name, where they start with the name and make dumb words up to fit it? The sort of "acronym" that sounds hilarious the first time you say it, and gets progressively less funny each time?

    The article doesn't give the names of any of the people involved in this, or any links where more detail can be found. Isn't it bad enough that researchers are paid crap; do they have to be anonymous too? How about giving these people some credit for their work.

    Is it just me or does the term "single milliwatt of power" sound odd? It seems to imply something discrete that comes in ones and twos and threes and so on. Why wouldn't you just say "a 1 mW light beam"?

    The structure in the current article is a ring resonator in this article. In the previous article the structure was a grating based resonator.
