摘要
分析了工艺制作过程中引入的阵列波导相位误差以及由其所引起的非相邻通道间串扰性能的劣化 ,给出了相应的分析公式 .利用该公式 ,可以简捷地分析所设计的 AWG型器件的非相邻通道串扰水平 ,为优化 AWG型器件的设计提供依据 .
Random phase errors of array waveguides induced by fabrication processing and their affects on crosstalk level of AWG based DWDM demultiplexer between non-adjacent channels are analyzed.A useful formula which can be used to estimate the crosstalk level of AWG devices is given.Using this formula,AWG based DWDM components can be optimized in order to reduce their crosstalk level.
