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 LiNbO3 and in III-V waveguides using the electro-optic effect1−3 and LiNbO3 using the photo-elastic effect.4
