Abstract

Single photon emitters in silicon carbide (SiC) are attracting attention as quantum photonic systems (Awschalom et al. Nat. Photonics 2018, 12, 516-527; Atatüre et al. Nat. Rev. Mater. 2018, 3, 38-51). However, to achieve scalable devices, it is essential to generate single photon emitters at desired locations on demand. Here we report the controlled creation of single silicon vacancy (V Si ) centers in 4H-SiC using laser writing without any postannealing process. Due to the aberration correction in the writing apparatus and the nonannealing process, we generate single V Si centers with yields up to 30%, located within about 80 nm of the desired position in the transverse plane. We also investigated the photophysics of the laser writing V Si centers and concluded that there are about 16 photons involved in the laser writing V Si center process. Our results represent a powerful tool in the fabrication of single V Si centers in SiC for quantum technologies and provide further insights into laser writing defects in dielectric materials.
