We describe our recent results demonstrating strong coupling between single rubidium atoms and a high-Q whispering-gallery-mode bottle microresonator. We observe clear signals of individual atoms passing through the resonator mode with interaction times on the order of several microseconds. Given this brief interaction time, we have implemented a real-time atom detection/probing scheme to enable experiments on this timescale. In particular, we investigate the light transmission and reflection characteristics of the strongly-coupled atom-resonator system. As an application of this system, we describe our progress towards the realization of a four-port device capable of routing photons between two optical nanofibers coupled to the resonator mode.
