Tiny Switch Flipped with Light

Facebook X LinkedIn Email
NEW HAVEN, Conn., Oct. 24, 2011 — Nanomechanical resonators can operate at amplitudes much higher than previously thought — a breakthrough in optomechanics that could have implications for future communications and sensing technologies. (Image: Wolfram Pernice, Mahmood Bagheri, Menno Poot and Hong Tang of Yale University) “We can flip a tiny switch with light,” said Hong Tang, associate professor of electrical engineering at Yale School of Engineering & Applied Science and the principal investigator of the new study. Amplitude refers to vibration range. Achieving high amplitudes in...Read full article

    laser cooling
    A process and method by which manipulation and orientation of a given number of directed laser beams decreases the motion of a group of atoms or molecules such that their internal thermodynamic temperatures reach near absolute zero. The 1997 Nobel Prize in Physics was awarded to Steven Chu, Claude Cohen-Tannoudji and William D. Phillips for the development of methods to cool and trap atoms with laser light.
    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.
