Photonics: Nanomechanics gets the shakes
Tobias J. Kippenberg1
Abstract
Photonic circuits can allow light to be tightly confined on a chip. A clever experiment reveals how this process can be exploited to create optical forces that drive a nanoscale mechanical oscillator.
In the 1970s, Arthur Ashkin at Bell Laboratories showed1 that the force that light exerts on an object — the radiation pressure force — can be used to trap particles. This discovery has led to a revolution in the use of lasers to trap objects ranging from atoms to biological cells.
