Morphology and lightguide property investigation of a high quality DAST single crystal

다국어 초록 (Multilingual Abstract)

A high quality 40-dimethylamino-N-methyl-4-stilbazolium tosylate single crystal with dimension of 7. 7 . 1 m m3 was grown inthis study. The polarized optic microscopy photograph showed that the surface of this crystal was ordered and at. Three-dimensional luminance image analysis demonstrated that the intensity of a guided laser light passing through the single crystal alongits molecular structure alignment is stronger than that guided along a standard 8.5/125l m silica optic ber. The diameter of thel m, re-spectively. The FTIR spectrum implied that the single crystal is more suitable for use as a communication window than the dis-ordered polycrystalline samples. The result reveals that without further processing the single crystal can be used as a waveguide andis a promising candidate for electro-optic modulators and other active optical devices.. 2002 Elsevier Science B.V.
