摘要: 采用转移矩阵法推导出内置LiNbO3光波导的FP腔滤波器的功率传输系数,运用计算机进行模拟计算,分析了光波导的传输损耗和腔薄膜反射率对滤波器透射光谱的强度、带宽和精细度的影响.结果表明,传输损耗越大,透射光谱的强度变小,带宽越大;反射率越大,透射光谱的强度变小,但带宽变小,精细度增大.考虑了滤波器的透射光谱强度和精细度等因素,提出一个合理的腔薄膜反射率,优化了滤波器的设计参数.

Abstract: With the transfer matrix method,the transmission coefficient of a F-P cavity filter with a LiNbO3 optical waveguide is reasoned out.By computer simulation,the effects of structure parameters of the F-P cavity filter on the transmission light intensity,bandwidth and finess are analyzed.The results show that the transmission light intensity becomes weaker and bandwidth becomes wider with the increasing of propagation loss,and that with the increasing of reflectivity,the transmission light intensity becomes weaker and the bandwidth becomes narrower,however the finess becomes increscent.The optimizing parameters of the F-P cavity filter are given by considering the transmission light intensity and finess.
