%0 Journal Article %T Strong coupling and long-range collective interactions in optomechanical arrays %A Andr¨¦ Xuereb %A Claudiu Genes %A Aur¨¦lien Dantan %J Physics %D 2012 %I arXiv %R 10.1103/PhysRevLett.109.223601 %X We investigate the collective optomechanics of an ensemble of scatterers inside a Fabry-Perot resonator and identify an optimized configuration where the ensemble is transmissive, in contrast with the usual reflective optomechanics approach. In this configuration, the optomechanical coupling of a specific collective mechanical mode can be several orders of magnitude larger than the single-element case, and long-range interactions can be generated between the different elements since light permeates throughout the array. This new regime should realistically allow for achieving strong single-photon optomechanical coupling with massive resonators, realizing hybrid quantum interfaces, and exploiting collective long-range interactions in arrays of atoms or mechanical oscillators. %U http://arxiv.org/abs/1202.6210v2
