a Side view of the whole system, where a diamond waveguide is inserted into a DBR cavity. The waveguide is fabricated on top of a DBR that acts as the bottom mirror of the cavity. The top mirror of the cavity consists of a fused-silica substrate, where a smooth crater is machined and a dielectric DBR coating is deposited. Further details of the cavity are described in ref. 53. b Zoomed top view of the waveguide inside the cavity. The emitters are linearly distributed inside the waveguide via deterministic Si+ ion beam implantation, cf. refs. 54,55. c Section views of the waveguide, where the locations of emitters inside the waveguide are specified. Emitters of B are slightly off-center to obtain a smaller emitter-waveguide coupling strength than that of A
