ABSTRACT:
A substrate has a pair of overlapping optical couplers for separately coupling a first and a second polarization component of a light beam into a first and a second waveguide channel. The channels are oriented with their longitudinal axis approximately perpendicular to each other. A first and a second optical detector are located in the first and second waveguide channels, respectively, for measuring the light intensity of the first and second polarization components.
