We are exploring novel ion traps using fabrication methods based on those used to create photonic crystal fibres (PCF). We fill the regular hole pattern of a pre-drawn PCF "cane" with gold wires that extend beyond the fused silica structure. The wire tips are used as the electrodes that form the ion trap. The production method used should allow fabrication of ion traps at various sizes, from 5 to 150 microns electrode diameter, and provide access to a number of different trap electrode patterns. This type of fabrication opens up new possibilities for realizing 2-dimensional arrays of ions for quantum simulations, and also results in a trap with high optical access which is suitable for combining with high-finesse cavities. I will describe our progress on trapping ions in a trap with a 130 micron electrode diameter.
