Description

Sub-wavelength arrays of atoms have been shown to have remarkable optical properties, like near perfect reflection and low diffraction loss. However, the collective effects resulting in these properties also serve to wash out the otherwise strong underlying nonlinearity of the atoms, rendering the arrays largely linear. We have found that by putting together two arrays we can recover a strong nonlinearity via an emergent cavity-like behaviour with a large delay time that allows photons to interact strongly before being emitted from the system. Such a quantum metasurface opens up new possibilities for manipulating non-classical light, from implementing quantum information operations to simulating many-body physics with interacting photons.
