键合型DANS聚合物光波导电晕极化及其二阶非线性衰减

CORONAPOLING AND SECOND ORDER NONLINEAR DECAY OF DANS SIDECHAIN POLYMER FILM WAVEGUIDES

对键合型ＤＡＮＳ聚合物薄膜光波导的电晕极化过程及其二阶非线性衰减特性进行了研究．采用本文给出的电晕极化参数，制成了具有较长极化寿命的极化聚合物薄膜光波导，为进一步研究其二阶非线性光学性质奠定了基础．

The coronapoling process and the properties of second order nonlinear decay of DANS polymer film waveguides were studied. The corona poled DANS (4dimethylamino4′nitrostlibene) sidechain polymer film waveguide having a long poling life had been fabricated by using the corona poling parameters in this paper, which laid a foundation for further study of its nonlinear optical properties.
