Abstract

Color centers in diamond attract a major attention due to their potential use in quantum information processing. In this work several methodologies to fabricate diamond based single photon emitters are presented: Ion implantation of an impurity into diamond nanocrystals grown by CVD technique or incorporation of an impurity during the CVD growth. The fabricated single photon emitters are photostable and exhibit narrow emission lines in the near infrared. Using sapphire as the growth substrate, ultra bright single photon emitters, with a single photon emission rate of up to millions of photons per second were fabricated by incorporating Cr atoms from the sapphire substrate. The presented tech..
