ANISOTROPIC SPECTRAL HOLES IN ORANGIC PHB MAERIALS

More than 300% anisotropic persistent spectral holes were written in and read out in some materials such as THP/PMMA and TMP/PMMA with high signal-to-noise ratio by CW linearly polarized light. The effect of probe angle and modulation field on the hole depth and hole shape were also interpreted by using polarisation spectra hole burning theroy.     

半花菁LB多层膜的光学非线性各向异性研究

用偏振紫外-可见吸收及旋转样品二次谐波（SHG）测量法研究了半花菁／花生酸Y型交替多层膜中分子在基极平面内分布的各向异性．拉膜过程引发的半花菁分子在平面内沿提拉方向的规则取向具有镜面对称性，并随着拉膜速度或层数的增大而增强．
