Electro-optic effects in the optically active compounds Bi12TiO20 and Bi40Ga2O63

Abstract

The electro-optic effects in the optically active 23 class compounds Bi12TiO20 (BTIO) and Bi40Ga2O63 (BGAO) have been investigated. Measurements were made of the electro-optic and electrogyration coefficients using longitudinal and transverse modes. Novel techniques employing a servo-driven Soleil compensator were used to obtain these coefficients. A value of η=17×10−12 rad m/V was obtained for the electrogyratory coefficient in the BTIO compound.
