Abstract:
The present invention provides an apparatus for measuring six polarization state of an input optical pulse. The disclosed apparatus is easy to implement with relatively lesser components to form the apparatus. The apparatus uses two polarization rotators (231, 232) having a respective non-linear material (221, 222) that are oriented at different angles. The two polarization rotators are connected in series for the polarization state on an input optical pulse and a beam splitter is connected thereafter to direct the rotated pulse to either a horizontal or a vertical detector.
