Paper Abstract

The polyisocyanate random copolymer containing an asymmetric chiral carbon center and Disperse-Red-1 nonlinear optical chromophores is synthesized. The optical activity is measured at the visible and near infrared spectral ranges, confirming the existence of the induced optical chirality in the copolymer film. Upon the application of a Corona field to the slab waveguide copolymer film, the polarization rotation at the wavelength of 1.3 micrometers is found to be changed, opening the possibility of the chiral electro-optic modulation in a chiral polymeric waveguide thin film.
