| 中文摘要 | glass spherical microcavities containing cdsse semiconductor quantum dots (qds) of a few microns in diameter are fabricated using a physical method. when a single glass microspherical cavity is excited by a laser beam at room temperature, very strong and sharp whispering gallery modes are shown on the background of pl spectra of cdsse qds, which confirms that coupling between the optical emission of embedded qds and spherical cavity modes is realized. for a glass microsphere only 4.6 mum in diameter, it was found that the energy separation is nearly up to 26 nm both for te and tm modes. with the increasing excitation intensity, the excitation intensity dependence of the emission intensity is not linear in the double-logarithmic scale. above the threshold value, the linewidths of resonance modes become narrower. the lasing behavior is achieved at relatively low excitation intensity at room temperature. high optical stability and low threshold value make this optical system promising in visible microlaser applications.
