Polarization rotation in asymmetric periodic loaded rib waveguides

Abstract

Polarization rotation is an important effect in integrated optics. It is required in balanced polarization diversity heterodyne receivers and in polarization controllers. Polarization rotation has been demonstrated in LiNbO 3 and in III-V waveguides using the electro-optic effect 1−3 and LiNbO 3 using the photo-elastic effect. 4
