Site-controlled InAs quantum dot for hetero-integration of single photon emitter

The site-controlled quantum dot was obtained for hetero-integration of single photon emitter with silicon photonic circuit and fiber optics. By using selective-area growth method, the InAs quantum dot was formed on the InP pyramid which showed single photon emission from 1100 to 1300 nm. The hetero-integrated structure was designed as InAs quantum dot on the silicon waveguides with high coupling efficiency and fabricated by micro-transfer technique.
