Nature: Optical detection of radio waves through a nanomechanical transducer

If you are a radio or electronics guy, this is very cool. From Nature journal (excerpt):

Many applications, from medical imaging and radio astronomy to navigation and wireless communication, depend on the faithful transmission and detection of weak radio-frequency microwaves. Eugene Polzik and co-workers introduce a new approach to detecting these signals, using a nanomechanical resonator that enables radio signals to be measured as optical phase shifts. Converting radio waves into light signals is an attractive proposition, as the signals can be transferred directly into standard optical fibres rather than copper wires, which may reduce losses and improve detection.

Note mention of wireless communication. Nature is a professional scientific journal. Access to full articles is only available to paid subscribers. (I only get the free excerpts – well worth monitoring!)
