摘要
利用Ｓｉ１－ｘＧｅｘ的等离子体色散效应，对１．３μｍ和１．５５μｍ光通信波长的Ｓｉ基Ｓｉ１－ｘＧｅｘ波长信号分离器进行了理论分析，设计了结构参数和电学参数，并分析了其分支特性．
Based on the plasma dispersion effect of Si 1- x Ge x , a systematic analysis and optimizing design were reported for the Si 1- x Ge x wavelength signal divider for the operation of optical communication wavelengths λ=1.3 and 1.55μm, On the basis of theoretical analysis, the structure parameters and electricity parameters of the WSD were designed and the branching charactertics were analyzed. The wavelength separation was demonstrated by crosstalks, waveguide losses and extinction ratios.
