摘要
利用一套ＣＣＤ显微荧光图像观测和采集分析系统，分别在室温和液氮温度下对半径为５μｍ发射波长０．６５μｍ的ＩｎＧａＰ半导体光学微盘的荧光图像进行了观测．在绿光激发下，观测到沿ＩｎＧａＰ微盘边缘内侧有一明亮的红色荧光光环和某些特征。
The fluorescence image of the semiconductor InGaP microdisk is observed and analyzed by a CCD fluorescence microscope system. Under green light excitation, a bright red ring of fluorescence near the edge of microdisk together with some features is observed. As a result, the images reveal the optical disk mode pattern in our InGaP microdisks dominated by Whispering Gallery modes mixed with other modes.
