The physics of coupled quantum emitters or strongly interacting polaritons in arrays of coupled cavities has attracted considerable interest in recent years. Yet experimental realisations, in particular with optical photons, are still scarce. Here we describe a technologically viable platform for experiments with atoms or other quantum emitters in coupled optical cavity arrays. The envisaged solution requires only existing fabrication techniques and realistic performance parameters. The device uses open Fabry-Perot micro-cavities to couple to the emitters. The central innovation of this design is to connect the micro-cavities via evanescently-coupled resonators on a photonic waveguide chip. Based on these premises we present a theoretical analysis of two possible experiments and discuss further, more advanced applications.
