A Vertically Loaded Diamond Microdisk Resonator (VLDMoRt) towards a Scalable Quantum Networks

This thesis reports a cavity design of vertically-loaded diamond microdisk resonator (VLDMoRt). It couples to a nitrogen-vacancy (NV) center in diamond for efficient collection of fluorescence emission into low numerical aperture (NA) free-space modes. The VLDMoRt achieves a Purcell enhancement of 172 with 39% of the emitted light collected within a NA of 0.6, leading to a total external spin-photon collection efficiency of 0.33. Furthermore, this design is demonstrated by established nanofabrication techniques, achieving a quality factor of > 2000. As the design is compatible with fabrications and couples to low-NA modes accessible by cryogenic free-space optical systems, it is a promising avenue for increasing the efficiency and scalability of quantum devices based on diamond quantum emitters.
