摘要：
By means of molecular beam epitaxy a single layer of self-assembled CdSe quantum dots (QDs) embedded in a ZnSe/ZnMgSSe heterostructure was grown on a GaAs substrate. Electron beam lithography and etching techniques were then applied to pattern microrings. Afterward the microstructures were glued on a glass support and the GaAs was totally removed. The photoluminescence of such glass supported rings was studied for different temperatures, and tuning of single QD lines into resonance with a cavity photon mode was achieved. Strong coupling was found with a Rabi splitting of 0.7 meV attributed to the strong oscillator strength of CdSe quantum dots. (C) 2008 American Institute of Physics. [DOI: 10.1063/1.2998403]
