The goal of this project is the demonstration of on-demand ideal photon pair generation for entanglement swapping at telecom frequencies employing quantum dots embedded in circular Bragg grating cavities. The InAs quantum dots in an InxGayAl1-x-yAs-matrix are grown by molecular beam epitaxy and the circular Bragg grating cavity will allow to tune the lifetime of the exciton and the biexciton as well as to enhance the emission efficiency. The experiments are supported and complemented by theoretical calculations to optimize device design and interpret results.
