| Abstract: | An all-optical format conveter based on polarization delay interferometer(PDI) is investigated.Accroding to the configuration design of the PDI,operation principle for CSRZ to Duoinary signal is analyzed,and numerically simulation proves that the presented scheme is feasible.The influence of differential group delay on the interference results is also investigated,it shows that inaccurate differential group delay will lead to degration of extinction ratio and receiver sensitivity of the output Duoinary signals. |
