| 摘 要： | 在Ti扩散铌酸锂光波导中,因光致折变效应而导致光波导特性漂移.在光波相干性的导波光学器件中,光致折变效应的影响尤为严重.本文报道了稳定光致折变效应的热固定技术实验结果;并提出在光波导特性的热固定过程中,不是H~+离子起主导作用这一看法.

| Abstract: | There is a characteristics drift caused by the photorefractive effect in Ti-diffused LiNbO3 waveguides. The drift will result in severe problems to the devices in pratical use, especially to that based on optical coherence principles. Experimental results about thermal fixing technique of waveguide characteristics are presented in this paper. It is derived from our experiment that H+ ions do not play an important role in thermal fixing processing. |
