浙江大学研究生学位论文用纸P Study on the Interference Characteristics of Multimode Optical Fiber and MMT Coupler WangWeiZhiI Dept.ofOpticalEngineering SupervisedbyProf.LongHuaiShen ABSTRACT Inthelatetenyears,opticalfibersensorshave shown their potential in physical sensing area.
浙江大学研究生学位论文用纸P Theinterference characteristics of the fieldsfrom MMF have been studied on two respects,one is on phase andtheotherisonpolarization.Inordertodescribe the behaviors of the light travelled along a fiber,we examinedthesuperpositionofelectromagneticfields of all guided modes.
