摘要
本文提出了阶跃折射率多模光纤的弯曲损耗的理论模型。用射线追踪法统一处理子午光线和偏射光线,即对各种角度的光线依次算出每次反射后的角度值和反射率,最后得到输出光功率,确定弯曲损耗,所得结果与实验一致。
In this paper bend loss in step-index multimode fibers is studied theoretically.Using ray tracing method we calculate angle parameters of rays and coefficients of reflection on every re- flection point,and obtain output optical power and bend loss finally.The results obtained agree well with the experimental ones.
