title: Optomechanical nanoantenna.
abstract: We introduce optomechanical nanoantennae, which show dramatic changes in scattering properties by minuscule changes in geometry. These structures are very compact, with a volume 500 times smaller than free-space optical wavelength volume. This deep subwavelength geometry leads to high speed and low switching power. The bandwidth of the device is about 4.4 GHz, with a switching energy of only 35 pJ. Such antenna structures could lead to compact and high-speed all-optical nanoswitches.
