Spin-active optical emitters in silicon carbide are excellent candidates toward the development of scalable quantum technologies. However, efficient photon collection is challenged by undirected emission patterns from optical dipoles, as well as low total internal reflection angles due to the high refractive index of silicon carbide. Based on recent advances with emitters in silicon carbide waveguides, we now demonstrate a comprehensive study of nanophotonic waveguide-to-fiber interfaces in silicon carbide.

Article Synopsis
  • Optically addressable spin defects in silicon carbide (SiC) show promise for quantum information processing due to their compatibility with semiconductor fabrication techniques.
  • Successful integration into nanophotonic structures is critical for scaling up to large quantum networks, but previous attempts have led to the degradation of spin-optical coherence.
  • This study presents successful implantation of silicon vacancy centers (V) in SiC that maintain strong intrinsic properties, achieving high-quality photon emission and stable spin-coherence, enabling controlled operations on nuclear spin qubits for advanced quantum communication.
