Abstract

This paper describes a polarization analyzer for the determination of the polarization state inside a single-mode fiber. Four different detection points formed by grinding off the cladding on one side of the fiber are used for measurement. A small part of the light is coupled out at these points and is measured by a standard photodetector placed just on top of the polished areas. At each of the detection points, a polarization dependent signal can be obtained. Hence, a relationship between these signals and the polarization at the end of the fiber can be found by calibrating this measurement instrument with a classical off-line polarization analyzer. Concluding we realized a measurement instrument which not only determines the polarization but also can adjust any wanted polarization state at the fiber output of the instrument.
