The usage of atomic vapors in technological applications has become increasingly relevant over the past few years. They are utilized e.g. in atomic clocks, magnetometers, frequency references or to slow down and store light. Integrated devices which combine photonic structures and thermal atomic vapors on a chip could be an ideal basis for such purposes as they provide efficient atom-light coupling on a miniaturized scale. Furthermore, the existing fabrication technology of photonic circuits allows for complex networking and multiplexing designs, potentially even at the single photon level. We report on the status of our work on various photonic structures integrated into a rubidium vapor cell. Specifically, we present our results on combining the atomic medium with Mach Zehnder interferometers [1], ring resonators [2] and slot waveguides. As the atoms are probed in close proximity to the dielectric material, atom-surface interactions and transit time effects play a substantial role.
