New Endless Polarization Control Method using Three Fiber Squeezers

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. Also a special controlling algorithm must be developed. Noe has proposed such an algorithm [6]-[8]. In this paper, a new theoretical approach to the problem is presented resulting in a new algorithm. The presence of angular misalignment between the fiber squeezers is also discussed.
