N1 - We thank János Perczel for insightful comments concerning the quantum description and dispersion relation of the array. We also acknowledge valuable discussions with Vladimir Shalaev, Markus Greiner, Peter Zoller, Darrick Chang, Hongkun Park, Alex High, and Kristiaan de Greve, and financial support from NSF and the MIT-Harvard Center for Ultracold Atoms.

N2 - We consider light scattering off a two-dimensional (2D) dipolar array and show how it can be tailored by properly choosing the lattice constant of the order of the incident wavelength. In particular, we demonstrate that such arrays can operate as a nearly perfect mirror for a wide range of incident angles and frequencies, and shape the emission pattern from an individual quantum emitter into a well-defined, collimated beam. These results can be understood in terms of the cooperative resonances of the surface modes supported by the 2D array. Experimental realizations are discussed, using ultracold arrays of trapped atoms and excitons in 2D semiconductor materials, as well as potential applications ranging from atomically thin metasurfaces to single photon nonlinear optics and nanomechanics.
