Fused Silica Ion Trap Chip with Efficient Optical Collection System for Timekeeping, Sensing and Emulation
Abstract
Goal was to develop Atom chips with dual integrated and miniaturized optical and electromagnetic capabilities. Proposed to fabricate traps out of fused silica, a material that is transparent at the wavelengths of interest (and which has good RF characteristic). Surmised that the material transparency would allow for optical beams to approach the trap from all directions. We also imagined that our demonstrated capability to fabricate numerous integrated optical elements in devices made from fused silica waters would provide the optical functionalities required for trap control and trap monitoring This approach was successfully demonstrated during our Phase 1. We fabricated a variety of microtrap geometries, concentrating on symmetric three-dimensional traps as these offer deeper trapping potential. We showed that we could also fabricate highly-shaped 3-dimensional electrodes. We showed that we could integrate or insert optical pathways and optical elements within the trap substrate and address the trapped ions from all directions. We demonstrated the fabrication of large NA fluorescence collection optics.
