Abstract
The present invention provides a polarization converter, and a method for fabricating the same. The polarization converter includes a geometric shape which induces rotation of a polarization of an optical signal from a first polarization state to a second polarization state as the optical signal propagates along the polarization converter. The performance of the polarization converter is maintained in light of inconsistencies in fabrication processes resulting in improved manufacturability.
