Abstract
A waveguide under test can be exposed to a light signal whose polarization rotates between the vertical and horizontal polarizations. The intensity detected at a photodetector can be separated into AC and DC components. The AC components may be utilized to derive a characteristics which is indicative of birefringence of the waveguide. If the light signal is scanned over the waveguide under test, a measure of the birefringence at each position along the waveguide may be determined.
