Key Details

•

Closely-spaced atomic arrays can exhibit superradiance and subradiance

•

Superradiance occurs below a critical lattice spacing that depends on array size

•

Superradiant peak intensity scales as N^1.2 for 2D and N^1.33 for 3D arrays

•

Subradiant phase appears after the burst before complete decay

•

Harnessing collective emission in ordered atomic arrays

This paper theoretically investigates the collective emission of light from ordered arrays of atoms spaced at sub-wavelength distances. It finds that closely-packed three-dimensional and two-dimensional lattices can exhibit superradiance, where the emission intensity scales faster than for independent atoms. The paper characterizes this cooperative phenomenon and shows it emerges below a critical lattice spacing. It also reveals a subsequent subradiant phase before the system decays. This provides new insights into harnessing many-body effects for quantum optics.
