摘要
对时域有限差分算法在圆柱坐标下弱导光纤中应用时吸收边界条件的设置及其对计算精度的影响进行了讨论,提出了改善的方法。并且将这种方法应用于一般光纤和光电子晶体光纤传输特性的计算,得到了有用结果。
Abstract
The application of CFDTD (cylindrical finite-difference time-domain) algorithm in the analysis of weak-guiding optical fiber and other types of fibers is discussed. Especially, the setting of the absorbing boundary condition and the calculation error are presented, improvement way is proposed. Further more, this method is applied to the calculation of propagation characters of optical fiber and the photonic crystal fiber, some useful results are given.
