摘要：

We present optical characterization measurements from three-dimensional pillar microcavities comprising an InP spacer layer sandwiched between two SiO2/Ta2O5 Bragg reflectors. InAs quantum dots placed at the center of the InP spacer are used as broadband emitters. Emission into the lowest-order mode is observed at an energy of 820 meV in the wide-pillar limit, with shifts of approximately 30 meV in the ground state and more than 80 meV in higher-order modes for pillars of 2 mum diameter. Excellent agreement is found between the experimentally observed cavity mode energies as a function of pillar diameter and the predictions of guided-mode theory. Cavity quality factors in excess of 2200 are obtained for large diameter pillars, with a decrease to approximately 500 for pillars of 2 mum diameter. (C) 2004 American Institute of Physics.
