Abstract
A polarization converter based on taking a high-order TE mode as a transition mode comprises a ridge waveguide () and a slab waveguide () that are arranged in double layers and varying in width, and a strip waveguide () which is varying in width. The ridge waveguide () is disposed on the upper end face of the slab waveguide (), and is aligned with two ends of the slab waveguide (). The right end of the ridge waveguide () and the slab waveguide () are connected with the strip waveguide () with the varying width. A TMmode enters from the left ends of the ridge waveguide and the slab waveguide, and is converted into a TEmode for output. On the contrary, the TEmode enters from the right end of the strip waveguide and is converted into the TMmode for output.
