Optomechanical Crystals
Researchers have created a nanoscale crystal device that, for the first time, allow scientists to confine both light and sound vibrations in the same nanoscale space simultaneously. The interactions between sound and light in this device-dubbed an optomechanical crystal-can result in mechanical vibrations with frequencies as high as tens of gigahertz, or 10 billion cycles per second. Being able to achieve such frequencies gives these devices the ability to send large amounts of information, and opens up a wide array of potential applications-everything from light wave communication systems to biosensors capable of detecting (or weighing) a single macromolecule. It could also be used as a research tool by scientists studying nanomechanics. The researchers describe the design, fabrication and characterization of a planar, silicon-chip-based optomechanical crystal capable of co-localizing and strongly coupling 200-terahertz photons and 2-gigahertz phonons.
