Abstract:
An optical integrated circuit, comprising:at least one waveguide extending axially between first and second ends, each waveguide having a centerpoint centrally located between the first and second ends, the at least one waveguide comprising a first portion between the first end and the centerpoint and a second portion between the second end and the centerpoint; a second waveguide extending axially between first and second ends and having a centerpoint centrally located on the second waveguide between the first and second ends, the second waveguide comprising a first portion between the first end and the centerpoint and a second portion between the second end and the centerpoint; a waveplate intersecting the at least one waveguide at an intersection spaced from the centerpoint, the intersection spaced from the centerpoint of the at least one waveguide by a first distance and the waveplate intersects the second waveguide at an intersection spaced from the centerpoint of the second waveguide by a second distance, the first distance and the second distance are approximately equal, the waveplate intersects the first portions of the waveguides; and an input lens providing light to the first ends of the waveguides and an output lens receiving light from the second ends of the waveguides.
