SBN:Cr晶体中孤子诱导的实时平面光波导及其导光特性分析

通过数值模拟和实验对SBN:Cr晶体中的（1+1）维亮屏蔽空间孤子及其诱导的实时平面光波导的导光特性进行了研究.采用分步束传播法和Petviashvili迭代法对（1+1）维亮屏蔽空间孤子的特性进行了模拟.通过求解本征方程,对孤子诱导平面波导中存在的导波模式进行了数值求解.采用633 nm的He-Ne激光作为孤子诱导光束,532 nm的半导体泵浦的固体激光作为探测光,在固液同成分的SBN:Cr晶体中进行了实验研究.实验结果和数值模拟的结果符合的很好.而且结果表明SBN:Cr晶体中红光诱导的波导可以作为实时光波导.

Soliton-induced Real-time Planar Waveguide and Its Guiding Property in SBN:Cr Crystal

One-dimensional (1D) bright screening optical solitons and the guiding properties of their induced planar waveguides are studied numerically and experimentally in SBN:Cr crystals.By employing the split-step beam propagation method and Petviashvili iteration method,1D bright screening solitons are numerically simulated.By solving the guiding modes,the guiding properties of the soliton-induced planar waveguides are analyzed.Using a He-Ne laser at 633nm as a soliton beam and a diode-pumped solid-state laser at 532nm as a probe beam,experimental demonstrations are performed in a congruent SBN:Cr crystal.The experimental results coincide with the numerical ones.And it is shown that the waveguide structures induced by red soliton beams can be used as real-time waveguides.
