COUPLING OF ORTHOGONALLY POLARIZED WAVES IN LINBO3 OPTICAL WAVE-GUIDES

Abstract

In LiNbO3 waveguides light is converted from ordinary to extraordinary polarization. We use a simple model to describe this effect, especially the dependence on the geometric properties (thickness, cut direction) of the waveguides. We report results for linear and circular photovoltaic tensor elements of iron- and copper-doped lithium niobate waveguides.
