Microtrap Fabrication Technology for
Trapped Ion Quantum Information Science
Microtrap connectivity and fibre integration
Microtrap connectivity across the UHV vacuum interface
- Microtrap chips mounted on industry-standard chip carriers
- Direct access of trap segments to DAC voltage control and RF drive
- Rapid chip change capability
NPL UHV feedthrough with microtrap on CCLC chip carrier and external drive circuit
Optical fibre integration with Microtrap (Aarhus)
- Cooling and probing light delivery direct to trapping region
- Ionization and loading via fibre-fed laser ablation of micro-pellet oven
- Fibre focussing via fibre tip profiling (heat-treatment of short silica splice to fibre end or writing a Fresnel grating directly onto fibre face)
