【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，表明ＩｎＧａＰ光学微盘中存在以回音壁模式为主导的多种模式混合的模式结构更多还原

【Abstract】 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.更多还原
