Optical field in tapered optical fiber is numerically simulated using 2D finite-difference time-domain (FDTD) method, optical character in different cladding radius is expounded.
然后用时域有限差分法（FDTD）数值计算了锥形光纤光场分布，论述了在不同的包层半径处，光纤锥的光场分布特性。
By the theory of ray optics, the bend losses of fiber as function of fiber parameters such as core index, cladding index, core radius and bend radius are set up.
利用光线理论研究光纤弯曲损耗与弯曲半径、纤芯折射中以及包层折射率的关系。
