摘要：
Photorefractive waveguides (PRWs) are fabricated by helium implantation in LiNbO3 doped via proton-assisted copper exchange. Fabrication conditions have been optimized to reach high diffraction efficiency of photorefractive holographic gratings. Fanning of the guided light is found to be a key factor limiting holographic recording performance in our newly developed waveguides. (C) 2001 Elsevier Science B.V. All rights reserved.
