Abstract
We present recent results aiming to construct single photon sources, detectors and gates using the integration of hot Rubidium atoms and microring resonators (MRRs). We demonstrate strong coupling between an ensemble of ≈53 atoms interacting with a high-Q (>4x10^5) cavity mode, with a many-atom coupling strength g/2pi≈1 GHz and cooperativity C≈3.6 achieved. A peak single-atom cooperativity C0≈0.4 is inferred; to achieve higher cooperativity, we have developed defect mode photonic crystal ring resonators with a 10x reduction in mode volume compared to the MRR while maintaining Q>10^5. Finally, we will discuss theoretical results that support single photon operations using these devices.
