Small glass cells filled with rubidium vapor are promising candidates for QIP based on a blockade mechanism between Rydberg atoms. In order to realize e.g. single photon sources based on vapor cells, cell dimensions in the order of the length scale of the Rydberg-Rydberg interaction (≈ 5 µ m) are required.
We present a method how to fabricate spectroscopy micro cells filled with rubidium vapor. In these cells the rubidium vapor is either confined to a 2D (quantum well) or a 1D (quantum wire) geometry. We performed measurements with a confocal microscope on structures ranging from 10 to 100 µ m. Two photon excitation (5S → 6D) provides a fluorescence signal that was spectrally analyzed. Wall induced spin changing processes could be identified.
