Abstract

Recording of holographic gratings in z-cut LiNbO₃ waveguides with extraordinarily (TM) polarized light is demonstrated. In this geometry, photovoltaic currents perpendicular to the guiding layer and the grating vector set up space-charge fields. The mechanism has no equivalent in bulk material.
