光纤波导场型分布的解析理论 ANALYTIC THEORY OF FIELD PARTTERNS IN FIBER OPTICAL WAVEGUIDES 朱秋萍 Zhu Qiuping 1 first-author 钮晋炜 Niu Jinwei 1 方志豪 Fang Zhihao 1 武汉大学电子信息学学院 武汉大学电子信息学学院 College of Electronic Information, Wuhan University College of Electronic Information, Wuhan University 全面推导出了光纤中４类导波模式的电力线和磁力线解析表达式，其中ＥＨｍｎ模和ＨＥｍｎ模给出了第１，２两组解的结果．同时，讨论了确定电力线和磁力线方向的方法．用计算机绘制了光纤导波模式的场型分布图． Analytic expressions of electric and magnetic lines for fiber waveguide modes are derived in this paper. Paticularly,the first and second group solutions for both EH mn and HE mn modes are completely given.Besides,the method of determining field direction is also discussed.Using these expressins,the electric field distributions are plotted.Finaly,the result is compared with that given by some publications. 光纤波导 导波模式 场型分布图 fiber optical waveguide waveguide modes field patterns TN929.11 国家教委面向二十一世纪教学改革科研基金 1997-05-01 2021-04-01 5
