摘要

研究了在硅辉石晶体基底上的平面光折变波导中光束的自作用。数值模拟证明了类孤子光束在平面Bi/sub 12/TiO/sub 20//Bi/sub 12/SiO/sub 20/外延波导中传播的可能性。在我们的研究中，我们假设一个(100)切割的Bi/sub 12/TiO/sub 20/晶体的方向，其中外场平行于[100]轴(z波导轴)，光波前沿[011]方向传播。推导了描述光束振幅分布演化的波动方程。

Bright spatial soliton in photorefractive planar Bi/sub 12/TiO/sub 20//Bi/sub 12/SiO/sub 20/ waveguide

Self-action of the light beams propagating in a planar photorefractive waveguide on the base of sillenite crystals is investigated. The numerical simulations demonstrate the possibility of soliton-like beam propagation in planar Bi/sub 12/TiO/sub 20//Bi/sub 12/SiO/sub 20/ waveguide fabricated by epitaxy. In our study we assume orientation of a (100)-cut Bi/sub 12/TiO/sub 20/ crystal in which the external field is applied parallel to the [100] axis (z waveguide axis) and optical wave front propagates along the [011] direction. The wave equations that describe the evolution of the amplitude distribution of light beam are derived.
