Query: Microfabricated high-finesse optical cavity with open access and small
  volume   We present a novel microfabricated optical cavity, which combines a very
small mode volume with high finesse. In contrast to other micro-resonators,
such as microspheres, the structure we have built gives atoms and molecules
direct access to the high-intensity part of the field mode, enabling them to
interact strongly with photons in the cavity for the purposes of detection and
quantum-coherent manipulation. Light couples directly in and out of the
resonator through an optical fibre, avoiding the need for sensitive coupling
optics. This renders the cavity particularly attractive as a component of a
lab-on-a-chip, and as a node in a quantum network.
