The coupled cavity device (CCD) consists of two ring resonators coupled by two waveguides. Each of the rings is \(6~\mu\mathrm{m}\) in diameter and the center-to-center distance between the rings is \(15~\mu\mathrm{m}\). A coherent input drive w is applied at one port, and the output field z is monitored at another port. The two remaining ports have a vacuum input and an unmonitored output field \(z'\). The SLH model of the CCD is described in the Appendix. The inset shows a magnified image of the device.
