Photonic-crystal fibre trap
Frieder Lindenfelser demonstrates Doppler cooling on a quadrupole transition in calcium, by power broadening the transition linewidth to be much larger than the trap frequency of the ion.
Paper published in Rev. Sci. Inst. describing our PCF trap, including design, fabrication and test results including heating rate.
Frieder Lindenfelser has built the first trap based on this new fabrication method (see photo). The structure was realized by pushing 130 micron gold wires through the glass "cane" structure produced by the Erlangen researchers. We will try to trap ions in this structure soon.

In a collaboration with the group of Philip Russell at the Max-Planck-Institute for the Science of Light in Erlangen, we are trying to build ion traps based on the fabrication methods for Photonic-Crystal-Fibres. The Russell group can fabricate structures from the millimetre to the nanometre scale. Current state of the art ion traps have dimensions which fall in this range, making this an appealing fabrication method with new possibilities.
