Abstract
Polarization coding is a specific encoding method by using the polarization state of optical signal carrying coded in -formation .It focuses on nonlinear effects ,polarization mode dispersion and other issues in high-speed fiber-optic communi-cations .This paper presents a measurement method for polarization state based on elastic -optic modulator .This method not only retains the original advantages of elastic-optic modulator for polarization measurement ,but also overcomes the defects of existing methods including high modulation frequency and invalid collection by using array detector .Matlab simulation and experimental verification scheme are given .The feasibility of this method is verified through theoretical analysis ,and simulation and experimental results are carried out .The error analysis of the measurement results shows that the method can meet the measurement requirements and provide conditions for using the polarization encoding in high -speed communication .关键词
