Single crystal diamond membranes that host optically active emitters are highly attractive components for integrated quantum nanophotonics. In this work we demonstrate bottom-up synthesis of single containing germanium vacancy (GeV) color centers. We employ a lift-off technique to generate the and perform chemical vapor deposition in presence source realize situ doping. Finally, show these suitable engineering photonic resonators such as microdisk cavities with quality factors ∼1500. The robust scalable approach engineer emerging centers is promising pathway realization nanophotonic circuits on chip.
