Paper Abstract

Integrated optics in LiNbO3 have been of great interest in recent years, devices such as e. g. modulators and switch matrices have been demonstrated. Most of them have however been polariza-tion dependent, which means that the chips must be excited with light in a specific linear polarization. In common single mode fibers, the state of polarization (SOP) is not constant along the fiber and typically in the end of a long fiber the SOP is varying randomly. One of the reasons for LiNbO3-devices being polarization dependent is that the electrooptic coefficient (r-coefficient) which determines the index change due to the applied electrical field is not equal for the TE- and TM-modes.
