利用溶胶 -凝胶低温合成非晶态技术 ,以正硅酸乙酯、N ,N -二甲基甲酰胺和乙醇为前驱体 ,将手性分子灰黄霉素均匀的掺入到上述体系的溶胶与凝胶中 ,成功的研制出了固体手性圆波导 ,并对其偏振响应作了测试 ,发现其偏振特性既不同于块状手性材料 ,也不同于固体非手性圆波导

Using TEOS,(CH3)2NCOH as precursor,the molecule griseofulvin was uniformly synthesized into the gel by sol-gel process.So a solid chiral circularwaveguide has been manufactured successfully.An experimental investigation is made on its polarity response.It is found that the polarization state is changed as compared with the bulk chiral medium and the solid circular waveguide.
