Abstract
A device for determining a polarization state of an electromagnetic wave includes a power splitter that splits an electromagnetic input wave into at least three partial waves; and at least three polarization converters for changing the polarization state of the partial waves. One of the polarization converters is associated with one of the three partial waves. The device includes an output coupler to which the partial waves are supplied after passing through the respective polarization converter and which includes at least three outputs. The output coupler is configured and the polarization converters are arranged and configured such that output waves exiting from the outputs of the output coupler have an intensity that each is dependent on one of the Stokes parameters of the input wave.
