AB - Pulse polarization switching is an important new method to eliminate the polarization-induced fading (PIF) in theinterferometric fiber sensing system. An integrated Ti-indiffused LiNbO3 Mach–Zehnder modulator is used to achievehigh-speed switch of the polarization state by switching the voltage between two appropriate voltages applied to themodulator. The stability of the polarization switching is affected by environmental factors, especially the temperature. Inthis paper, the stability of the polarization switching is studied. Firstly, the structure of the modulator and the principle ofthe polarization switching are introduced. Secondly, a feedback control method to overcome the switch instability isproposed. The output polarization state could be obtained by monitoring the intensity of the output light. Finally, thehigh-speed and high-accuracy stable switching between two orthogonal polarization states is realized using this methodand experimentally demonstrated.
