New research by engineers at the Yale School of Engineering & Applied Science demonstrates that nanomechanical resonators can operate at much higher amplitudes than previously thought. The results represent an advance in optomechanics, in which the force of light is used to control mechanical devices. The findings could have implications for future communications and sensing technologies.
The operating principle is similar to the laser cooling technique used in atomic physics. One can control the motion of a mechanical structure, amplify or cool its vibrations, just by controlling the wavelength of laser light.
Among other benefits, optomechanical memory devices can withstand harsher environments than electronic or magnetic memory devices, without losing data.
