Application and Improvement of Finite-difference Time- domain Algorithm in the Analyses of Optical Waveguid
摘要
对时域有限差分算法在弱导光纤中应用时吸收边界条件的设置和计算结果的误差进行了讨论,并提出改善计算精度的方法.文中给出用这种方法计算普通光纤传输特性的结果.
Abstract
In this paper,we discuss the application of CFDTD (Cylindrical Finite Difference Time Domain)algorithm in the analyses of weak guide optical fiber.Especially,the setting of the absorbing boundary condition and the error of the result are discussed.We present a way to improve the accuracy of the algorithm.Finally,the propagation characters of optical fiber are given in the paper.
