Abstract

We couple InAs quantum dots embedded in a pinin diode to circular bragg gratings, i.e. bullseye cavities. We observe a large Purcell enhancement by a factor of about 15, and an 80% dip in the cavity reflectivity at the quantum dot wavelength. Thus, these devices are promising as single photon sources and repeater nodes in a quantum network.
