摘要

本文给出了在Bi/sub 12/SiO/sub 20/衬底上形成的平面光折变波导Bi/sub 12/TiO/sub 20/吸收系数变化的实验观察结果。通过熔融结晶，在Bi/sub 12/SiO/sub 20/单晶衬底上生长出了具有高光学质量的Bi/sub 12/TiO/sub 20/薄膜。波长为/spl λ /=0.63 /spl mu/m的氦氖激光通过波导传播，以红光和绿光二极管作为背景照明。我们研究了低数(1-3)和高数(7-10)波导模式在背景光照和无背景光照下的光致效应。

Photoinduced absorption in a planar BTO/BSO waveguide

We present the results of experimental observation of the dynamics of the absorption coefficient changing in the planar photorefractive waveguide Bi/sub 12/TiO/sub 20/ formed on Bi/sub 12/SiO/sub 20/ substrate. The Bi/sub 12/TiO/sub 20/ film with high optical quality was grown on a substrate of single-crystal Bi/sub 12/SiO/sub 20/ by crystallization from the melt. The radiation of helium-neon laser with the wavelength /spl lambda/=0.63 /spl mu/m was propagated through the waveguide, the light of red and green light-diode was used as background illumination. We investigate the photoinduced effect for low-number (1-3) and high-number (7-10) waveguides modes with background illumination and without one.
