Abstract
Optical clocks based on trapped ions are highly stable frequency standards with applications in navigation, fundamental physics tests, and chronometric geodesy. Hence, ion traps are a key component for ion-based quantum technology applications. To achieve greater scalability and laser pointing stability, it is crucial to integrate nanophotonics monolithically into ion trap architectures. Addressing and manipulating the ions requires wavelengths ranging from ultraviolet (UV) to near-infrared (NIR). In this contribution, we report on the design and characterization of a photonic integrating circuit for the optical addressing of Yb+ ions using a foundry-fabricated single-layer Al2O3 nanophotonic platform.
