OLCHING, Germany, Jan. 14, 2016 — The PSY-201 PolaFlex deterministic polarization controller from General Photonics Corp. adjusts the polarization of light in 9/125-μm single-mode fibers in a targeted manner for use in optical transmission or fiber sensors. A polarization controller is combined with an in-line polarimeter with sophisticated control algorithms. The PolaFlex modulates fluctuations in the input polarization to achieve the desired and stabilized polarization state at the instrument's output. The device can also be used as a polarimeter to determine the current state of polarization and measure the degree of polarization. As a polarization synthesizer, it produces any state desired or runs programmed polarization traces on the Poincaré sphere. Alternatively, the PolaFlex can be used as a polarization scrambler. Laser Components GmbH is the distributor.
