Abstract

We present an experimental approach to study low light level absorption in a tapered optical fiber embedded in a rubidium atomic vapor medium. Our initial measurements demonstrates the potential of the system to realize extremely low light level quantum interference effects in the ultra small mode volume of the thin fiber, which is promising for many practical integrated device applications. The measurement shows saturated probe absorption using a low optical power of only ten nanowatt. Efforts are underway to use the fiber in a cloud of trapped rubidium atoms, which will circumvent the transit time limit for demonstrating a low photon optical switch via quantum interference.
