Abstract

Color centers in nanodiamonds coupled to nanophotonic structures feature unique properties to realize high-bandwidth quantum photonic devices. They exhibit photostable and narrowband single-photon emission. Their natural compatibility with plasmonic resonators unlocks a giant enhancement of light-matter interaction and photon emission rates up to the THz range. Color centers in nanodiamonds can be integrated onto any robust photonic platform. However, the sizes of nanodiamonds and the heterogenous properties of color centers pose challenges for device fabrication. Recently, innovative methods for nanodiamond growth, large-scale screening, and deterministic nanoparticle transfer have been developed. In this context, we will zoom in on our recent demonstrations of rapid techniques for large-scale optical screening of quantum emitters, including automatic confocal microscope focusing in a noisy environment and nanodiamond sizing.
