| Popis: | The 4H-silicon carbide (SiC) shows the capability to host a large number of promising emitters for quantum technology. However, due to its high refractive index, the collection of photoluminescence emission is compromised for further applications. Here, we demonstrate a scalable approach of manufacturing solid-immersion lenses (SILs) on 4H-silicon carbide (SiC). The fluorescence collection efficiency of single quantum emitters under the SILs shows 3.4 times enhancement confirmed by confocal microscopy of individual colour centers RK acknowledges financial support by DFG (Grant No. KO4999/3-1).
