Based on the analysis of the single-ring resonator, both the transfer functions of parallel-coupled structure and the ones of series-parallel structure in multiple-ring high order resonators are derived using the transfer matrix method. And the influences of the length of straight waveguide between rings, coupling coefficients between rings, coupling coefficient between straight waveguides and ring, the number of rings and the radii of rings on spectral response are also analyzed. Spectral response at drop channel with maximally flat response pass bands and sharper roll-off could be achieved by optimizing these parameters, so as to improve the performance of output spectral response.

在分析单环结构的基础上，利用传输矩阵法，推导了多环并联和多环串联两种耦合结构的高阶谐振器的传输函数公式，分别分析了并联环间直波导的长度、串联环间耦合系数、环与直波导间的耦合系数、环个数和环半径对相应结构输出特性的影响，通过优化这些参数实现下话路输出光谱具有通带的最大平坦性和过渡带良好的滚降特性，从而达到改善其输出光谱特性的目的。
