Determination of polarization dependent properties

An optical receiver for determining a polarization dependent property of an optical device under test that is provided with an optical stimulus signal comprising:

• a first receiver adapted for receiving a response signal from the device under test in response to an optical stimulus signal having a reference state of polarization,
• a polarization evaluator adapted for determining an output state of polarization of the response signal,
• a second receiver adapted for receiving a reference information about the reference state of polarization, and
• an optical property evaluator adapted for determining the polarization dependent property on the base of the reference information, a predefined function describing the dependency of reference information versus the reference state of polarization, and the output state of polarization.
