摘　　要：提出一种新型的光子晶体双色谐振腔，以光学传输矩阵法为基础给出了设计的关键参量及其优化方法，并分析了其物理原理．根据常用的650nm／780nm，532nm／671nm，1079nm／1320nm和1064nm／1319nm等双色激光谱线，设计了4个光子晶体双色谐振腔结构．这种一维光子晶体谐振腔只需要一个谐振腔，缺陷层两侧周期数为5层时，该腔体总厚度小于5μm，可获品质因子为10^3～10^4，相对带宽为10^-4～10^10的双色谱线，且模式纯净，基于基模谐振．A new double-wavelength photonic crystal resonator is presented. Design approach, key parameters and optimizing method based on the optical transmission method are summed up. Examples for designing the resonator with doublewavelength of 650 / 780 nm, 532 / 671 nm, 1079 / 1320 nm, 1064 / 1319 nm are given. It is different from a traditional Fabry-Perot resonator in that there is only one resonator in the doublelwavelength system with a much smaller volume （with a thickness less than 5 microns） ,it operates on the basis of fundamental modes with higher efficiency,and it has a higher quality factor with no stray modes. Simulation comes out that the relative bandwidth of the spectrum is less than 10^-3 and quality factor higher than 10^3 for a structure with 5 periods at either side of the defect layer.
