Recently, the propagation characteristics of waveguides or fibers filled with homogeneous chiral media were studied widely. But most of the chiral molecule was at the state of liquid. So further basic research and application research has been restricted and seeking suitable solid chial material was becoming the key of minimizing and practical development. One way of manufacture solid chiral material is sol-gel method. In this paper, using TEOS, C2H5OH and N, N-dimethyl formamide dimethyl aceta as precursor, the chiral molecule C17H17ClO6 was uniformly incorporated in gel by sol-gel process. So the sol-gel material containing C17H17ClO6 was fabricated successfully. Its polarization response was investigated. By using several different kinds of light sources which own different wavelength, we test the optical rotatory dispertion of chiral sol-gel material containing C17H17ClO6. By calculation, we obtain chiral parameter at different optical wavelength. In order to find out which state the chiral molecule C17H17ClO6 maybe in the sol-gel material, the infrared absorption spectra are measured.
