In a photonic crystal, the periodicity of the host medium is used to manipulate the properties of light, whereas in a phononic crystal it is mechanical vibrations that are subject to such control. Here, a structure that acts as both a photonic and phononic crystal — an 'optomechanical' crystal — is described; the strong coupling between photons and phonons realized in this structure should find application in a host of sensing and communication technologies.
