In optical telecommunications and fiber sensor technology, it is often necessary to determine the polarization of light in a fiber and influence it in a targeted manner in order to minimize polarization-dependent effects, for example.
The deterministic polarization controller PSY-201 PolaFlex™ from General Photonics makes it possible to adjust the polarization of light in 9/125 µm single-mode fibers in a targeted manner. This is achieved through the combination of a polarization controller and an inline 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 PolaFlex™ can also be used as a polarimeter to determine the current state of polarization (SOP) and measure the degree of polarization (DOP). As a polarization synthesizer, it produces any state desired or runs preprogrammed polarization traces on the Poincaré sphere. Alternatively, the PolaFlex™ can also be used as a polarization scrambler.
The PolaFlex™ is used in optical transmission technology or fiber sensor technology to characterize the polarization properties of optical components and receivers, to monitor the current state of polarization, or to measure the polarization extinction ratio.
