摘要

利用时域有限差分(FDTD)输出的pad近似和Baker算法得到的传输系数的相移，计算了光在耦合微环波导结构中的传输时延。研究结果表明，pad近似是时域有限差分仿真中节省时间的有力工具。

Calculation of light delay by FDTD technique and Padé approximation

The time delay for light transmission in a coupled microring waveguide structure is calculated from the phase shift of the transmission coefficient obtained by Padé approximation with Baker's algorithm from FDTD Output. The results show that the Padé approximation is a powerful tool for saving time in FDTD simulation.
