Polarization angle of the output ellipse (cf. Fig.8) for the left output when injecting into the left and right input, respectively. For the input, we used the linearly polarized HeNe laser at 3.39 μm at different polarization angles (depicted on the x-axis). The dashed line depicts an unaltered polarization angle. Qualitatively, there is very little or no difference between the two output polarization angles.
