Research on voltage-controlled polarization controller in the polarization mode dispersion compensation experiment

摘要

A kind of voltage-controlled polarization controller made in electro-optic materials is studied in the experiment. By changing voltages added on the different plates, the corresponding out states of polarization are gotten which spread all over the Poincare'. Results show that the phase retardation angle in each plate is a quadratic function of the applied voltages. And the degrees of polarization ellipsoids are obtained with the same the principal state of polarization. PC, a key element in the communication system, has great advantage for Polarization mode dispersion compensation and accurate controlling to the states of polarization.
