Optical Detection of Radio Waves

Caption: In this artist's impression of the device, radio waves (green) arrive and are sent to the membrane (center) via gold wires. This induces charge oscillations on the 4-segment electrode right underneath (~1 Ám distance) the membrane. Electric forces thus make the membrane move. This motion is detected with a laser beam (red), with an extreme accuracy (1 femtometer per second measurement time), translating to a very high sensitivity to radio waves.
