As part of the EU project "QU-PIC," we aim to develop scalable photonic integrated circuit (PIC) modules designed to meet the stringent requirements of quantum sensor applications. These modules will feature multiwavelength tunable lasers ranging from UV to the near-IR, specialized light conditioning systems, and photonic-integrated ion trap chips, all engineered for the realization of an ion trap-based quantum sensor demonstrator. This talk will give an overview of the individual components and detail on ring resonator couplers for PIC-based lasers and grating outcouplers based on an Al2O3 platform, using benchmarking protocols for 3D beam tomography of the PIC-based ion-trap system.
