| 英文摘要 | The exact calculation of mode quality factor q is a key problem in the design of high-q photonic crystal nanocavity. on the basis of further investigation on conventional pade approximation, fdm and dft, pade approximation with baker's algorithm is enhanced through introducing multiple frequency search and parabola interpolation. though pade approximation is a nonlinear signal processing method and only short time sequence is needed, we find the different length of sequence requirements for 2d and 3d fdtd, which is very important to obtain convergent and accurate results. by using the modified pade approximation method and 3d fdtd, the 2d slab photonic crystal nanocavity is analyzed and high-q multimode can be solved quickly instead of large range high-resolution scanning. monitor position has also been investigated. these results are very helpful to the design of photonic crystal nanocavity devices.
