Arrays of waveguide-coupled optical cavities that interact strongly with atoms

Abstract

We describe a realistic scheme for coupling atoms or other quantum emitters\nwith an array of coupled optical cavities. We consider open Fabry-Perot\nmicrocavities coupled to the emitters. Our central innovation is to connect the\nmicrocavities to waveguide resonators, which are in turn evanescently coupled\nto each other on a photonic chip to form a coupled cavity chain. In this paper,\nwe describe the components, their technical limitations and the factors that\nneed to be determined experimentally. This provides the basis for a detailed\ntheoretical analysis of two possible experiments to realize quantum squeezing\nand controlled quantum dynamics. We close with an outline of more advanced\napplications.\n
