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