Abstract
The present invention relates to a waveguide structure, and methods for making the same. The waveguide structure has a polarization rotator for rotating the polarization of the electromagnetic signal, preferably by about ninety-degrees. In one embodiment, the polarization rotator has a midsection with a first level and a second level. The first level of the midsection has a width that decreases along the length of the first level, while the second level has a substantially constant width along the length of the second level. Further, the waveguide structure can include an input conditioning section and the output conditioning section to facilitate matching between the polarization rotator and other waveguide elements.
