COMPENSATION OF THE PHASE SHIFT OF THE COUNTERPROPAGATING SIGNALS IN NONLINEAR OPTICAL MIRROR

研究利用基于非线性光环境 ( NOLM)的波长变换器实现非归零 ( NRZ)码的波长变换 ,对基于 NOL M的波长变换器进行理论分析 ,指出由于 NOLM中引入的反向光相移的影响 ,无法实现 NRZ码的波长变换 ,给出了对反向光相移进行补偿的方法 ,通过计算指出 ,补偿反向光相移后可以实现 NRZ码的波长变换 .

Wavelength conversion of NRZ signals using NOLM (Nolinear optical loop mirror) is investigated.Mathematical analysis of wavelengthconverter based on NOLM suggests that wavelength conversion of NRZ signals can not be obtained because of the phase shift of counterpropagating light.Methods to compensate the phase shift of counterpropagating signals are described.Mathematical analysis shows that wavelength conversion of NRZ signals can be obtained by compensate the phase shift of counterpropagating light.
