All-optical transistor
Date:11/11/2010

o-vibration conversions are already widely used; in mobile phones, for example, a receiver converts electromagnetic radiation to mechanical vibration, enabling the signal to be filtered efficiently. But it has been impossible to do this kind of conversion with light. With an OMIT-based device, an optical light field could for the first time be converted into a mechanical vibration. This could open up a huge range of possibilities in telecommunications. For example, novel optical buffers could be designed that could store optical information for up to several seconds.

On a more fundamental level, researchers around the world have been trying to find ways to control optomechanical systems at the quantum level: the switchable coupling demonstrated by the EPFL-Max Planck team could help the community clear this hurdle, by serving as an important interface in hybrid quantum systems.
