Abstract

This paper is concerned with the noncentrosymmetric alignment of betaine molecules dispersed in a polymeric matrix by an all-optical poling process. Two types of betaine molecules were used: one is betaine-azo with an azobenzene moiety in the molecule and the other is betaine-C8 without an azobenzene moiety in the molecule. The effect of the azobenzene moiety in the molecule on the optical poling efficiency, the formation of Χ(2) structure, and its thermal stability was studied. Optical anisotropy of the Χ(2) tensor components formed in the matrix in the writing process with linearly polarized beams was evaluated by rotating a sample film or rotating the polarization direction of the fundamental reading beam.
