Patent abstract

A polarization coupler includes a stress-inducing feature disposed to generate a stress-field in a substrate. First and second waveguides each have a coupling portion that pass through the stress-field. First and second periodic-structures are in optical communication with the coupling portions of the first and second waveguides.
