Paper Abstract

We demonstrate an integrated photonic platform for control of complex atomic systems. The platform includes multiple waveguide layers and a suite of passive photonic circuit components supporting a wavelength range from 370-1100 nm. In particular, we demonstrate a novel dual-layer vertical grating coupler used for efficiently directing visible light to precise positions above the chip surface. These circuits are compatible with traditional CMOS fabrication techniques and are well suited for improving the scalability of quantum information processing systems based on trapped-ion technology. A chip-scale waveguide platform at visible wavelengths could also prove useful in a variety of bio-photonic and sensing applications requiring precise light delivery or readout in a compact footprint.
