High-Efficiency Free-Space Coupling from Diamond Microdisks for Scalable Spin-Photon Interfaces
We present a dual-layer grating perturbation design integrated with a microdisk resonator. This design achieves vertical emissions with 95% Gaussian far-field overlap and 97% collection efficiency at the numerical aperture of 0.7. Using a dipole approximation method, we optimize the design for scalable quantum networks.
