英文摘要
We have prososed and fabricated metal-embedded GaAs pillars with InAs quantum dots inside. Initially titanium was used for the fabrication of the metal-embedded structure and the photon extraction efficiency to couple to lens (NA=0.4) of 8% was observed. Later metal was changed to silver and the much higher efficiency of 18% was achieved. The single photon generation purity can be examined with the second-order photon correlation function g(2)(0), and the world-record level 0.02 was observed under non-resonant excitation and the lower value of 0.007 was observed under quasi-resonant excitation.
