英文摘要	The pade approximation with baker's algorithm is compared with the least-squares prony method and the generalized pencil-of-functions (gpof) method for calculating mode frequencies and mode q factors for coupled optical microdisks by fdtd technique. comparisons of intensity spectra and the corresponding mode frequencies and q factors show that the pade approximation can yield more stable results than the prony and the gpof methods, especially the intensity spectrum. the results of the prony method and the gpof method are greatly influenced by the selected number of resonant modes, which need to be optimized during the data processing, in addition to the length of the time response signal. furthermore, the pade approximation is applied to calculate light delay for embedded microring resonators from complex transmission spectra obtained by the pade approximation from a fdtd output. the prony and the gpof methods cannot be applied to calculate the transmission spectra, because the transmission signal obtained by the fdtd simulation cannot be expressed as a sum of damped complex exponentials.
