Abstract
Photorefractive planar waveguides have been fabricated in cerium-doped strontium barium niobate (SrxBa1-xNb2O6, SBN) single crystals by ion- beam implantation. The losses measured were as low as 0.1 and 7.0 dB c m(-1) for the TM and the TE modes, respectively. Subsequent two-beam-c oupling experiments performed on the waveguides showed that, unlike fo r BaTiO3 and KNbO3 waveguides formed by ion-beam implantation, the two -beam-coupling gain direction did not reverse. Also, the response time had been reduced by 2 orders of magnitude. (C) 1996 Optical Society o f America
