| Abstract(in English) | Recently, considerable attention has been paid to the development of polymeric electro-optic (EO) materials due to their potential applications in ultra-high-speed optical modulators and switches, digital signal processing, and electric-field sensors. The EO polymers with a large EO coefficient r_<33> over 100 pm/V have been developed by using EO chromophores with large molecular first hyperpolarizability and excellent thermal and chemical stability. Several techniques for characterizing EO performance have been developed. Among these methods, the reflection ellipsometric method has been most commonly used due to the simplicity of its measurement procedure and its sample preparation. On the other hand, some drawbacks of this method are pointed out both from practical and intrinsic viewpoints. Without greater care, the obtained data by this method can lead to inaccurate results. In this paper, we have developed the transmission ellipsometric method without an aperture for simple and reliable evaluation of the EO coefficient r_<33> of EO polymers. |
