Title: Fiber squeezer polarization controller with low activation loss

Abstract: An improved polarization control method and apparatus is provided. The described invention uses super-polished squeezing surfaces to apply pressure thereby minimizing micro-bending effects that cause losses in the fiber. Special control circuitry has also been designed to maintain a driving source of piezo-electrics that control the squeezing surfaces at a resonant frequency, thereby minimizing the voltages needed to drive the piezo-electrics.
