ABSTRACT
Chiral isotropy material should be obtained in order to manufacture chiral optical waveguide. In the present paper, a chiral crystal of NaClO3 was grown from water solution by standard rocking techniques. Crystal incising and optical polishing were doneand a transparent 10.9 mm x 8.2 mm x 4.7 mm crystal NaClO3 was obtained. Along the six directions perpendicular to the surface of the crystal NaClO3, its circular dichroism and UV spectra were collected, and at the same time its optical rotatory dispersion was measured by a self-fabricated ORD apparatus. It was approved by our experiment that the CD, UV spectrum and the optical rotatory dispersion of the crystal NaClO were isotropic, which is not the same as those of quartz.
ABSTRACT
The polarization-sensitive effects of solgel materials containing various chiral media were measured experimentally. The results show that the solgel material displays optical activity when it contains organic chiral molecules and manifests depolarization when it contains inorganic chiral microcrystals with a particle size of 70 microm. Solgel material containing glass powder that also has a particle size of 70 microm displays a polarization held characteristic (i.e., the polarization of the output light is the same as that of the input light).
