Addressing spectrally distinct individual SiV^– hosted in the same nanostructure. (a) crf-PLE measurement revealing three resonances, which we attribute to C transitions of three distinct SiV^– within the same parabolic reflector (PR). The inset illustrates such a situation. (b) Off-resonant g⁽²⁾(τ) on the PR in question, showing that indeed, more than one emitter is being addressed. (c) Resonant g⁽²⁾(τ) of each individual resonance shown in (a) obtained by subsequently tuning the 737 nm laser into each resonance and collecting (PSB) photons. These data show the ability to address one individual emitter in a multi-emitter nanostructure, increasing the yield of scanning probes in a sample.
