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.
