摘要
采用物理吸附方法制备出多孔硅和偶氮化合物染料分散红(DR1)的复合薄膜.用单光束扫描法研究了多孔硅/DR1复合膜的三阶非线性光学性质,测量了在1064 nm处多孔硅/DR1复合膜的双光子吸收系数和非线性折射率.实验结果表明,同多孔硅相比,多孔硅/DR1复合膜三阶非线性光学效应明显得到了增强.
Abstract
The porous silicon and push-pull azobenzene compounds disperse red 1 (DR1) composite films have been prepared by physical adsorption method,and the third optical nonlinearities of samples were studied by single beam technique(Z-scan ) in this paper.The nonlinear absorption and nonlinear refractive index of porous silicon/DR1 composite films at 1064nm have been measured respectively.The experiment results show that optical nonlinearity in porous silicon/DR1 composite films is enhanced obviously compared with porous silicon.
