N2 - We show that single InAs quantum dots embedded in a planar cavity, formed by mismatched sets of GaAs/AlAs distributed Bragg reflectors, can be a useful source of triggered single photons as well as polarisation-entangled photon pairs. The former is demonstrated with a second order correlation function under 0.1 and the latter with a fidelity exceeding 70%. Such quantum dot devices may be useful in quantum communications and quantum information processing.
