Abstract

In the past few years, efforts to manufacture small atomic vapor cells have intensified, making it possible to build small, integrated frequency references, miniature optical clocks, and micron and nanometer sensors. In this direction and in order to increase the interaction of light and thermal alkali vapors, the optical interactions of the evanescent field with low optical power have been investigated in a micro-tapered fiber embedded in hot rubidium vapor. The results of transmission spectroscopy in these emerging cells show increased broadening compared to standard rubidium atomic vapor cells. In these micrometer systems, the possibility of nonlinear optical interactions with powers of milli watt-level is provided, despite the broadening of the transition-time much larger than the intrinsic broadening of the atom.
