A Large-Scale GaP-on-Diamond Integrated Photonics Platform for NV Center-Based Quantum Information

Abstract

We present chip-scale transmission measurements for three key components of a GaP-on-diamond integrated photonics platform: waveguide-coupled disk resonators, directional couplers, and grating couplers. We also present proof-of-principle measurements demonstrating nitrogen-vacancy (NV) center emission coupled into selected devices. The demonstrated device performance, uniformity and yield place the platform in a strong position to realize measurement-based quantum information protocols utilizing the NV center in diamond.
