New endless polarization control method using three fiber squeezers

Abstract

In a polarization control system using two fiber squeezers of limited range, the reset causes momentary signal loss. To prevent this loss, an extra squeezer is required and a special controlling algorithm must be developed. A theoretical approach to the problem is presented resulting in such an algorithm. The presence of angular misalignment between the fiber squeezers is also discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
