Efficient Fiber Optic Detection of Trapped Ion Fluorescence

VanDevender, A. P., Colombe, Y., Amini, J. et al.

Understand

Integration of fiber optics may play a critical role in the development of quantum information processors based on trapped ions and atoms by enabling scalable collection and delivery of light and coupling trapped ions to optical microcavities.

  • We trap 24Mg+ ions in a surface-electrode Paul trap that includes an integrated optical fiber for detecting 280-nm fluorescence photons.
  • The collection numerical aperture is 0.37 and total collection efficiency is 2.1 %.
  • The ion can be positioned between 80 \mum and 100 \mum from the tip of the fiber by use of an adjustable rf-pseudopotential.
