Physicists skirt thermal vibration, transfer optical signal via mechanical oscillator

November 15, 2012

From the group of Hailin Wang

Using tiny radiation pressure forces — generated each time light is reflected off a surface — University of Oregon physicists converted an optical field, or signal, from one color to another. Aided by a “dark mode,” the conversion occurs through the coupling between light and a mechanical oscillator, without interruption by thermal mechanical vibrations.
