[15a-B414-3] Wavelength dispersion of electro-optic coefficients in LiTaO3: method of finding dispersion curve from one measurement value

Kuniharu Takizawa1 (1.Seikei Univ.)

Keywords:linear electrooptic coefficient, quadratic electrooptic coefficient, wavelength dispersion

Using electro-optic coefficients in LiTaO3 measured at wavelength 632.8 nm and the wavelength dispersion curves of EO coefficients in LiNbO3, low- and high-frequency EO dispersion curves in LiTaO3 were deteremined. The low frequency dispersion curves of r13 and r33 in LiTaO3 were in good agreement with the EO coefficient values measured by Casson et al. [J. Opt. Soc. Am. B/21 (2004) 1948] at the near infrared region.
