Abstract :
A fast polarization control system using a lithium niobate electrooptic polarization transformer and a simple electronic feedback circuit is reported. The system produces general elliptical phase retardation at a maximum rate of 6300 rad/s and allows continuous transformations from any general varying input polarization into any desired output state. The automatic stabilization of a rapidly varying polarization state at rates of up to 4900 rad/s was achieved.<>
