Abstract

The quadratic electro-optic effect in K_0.95Na _0.05Ta_1-xNb_xO₃ crystals near the Curie temperature was investigated. Both the electro-optic coefficients |R ₁₁| and |R₁₂| decreased rapidly as the temperature increased beyond the Curie point. Interestingly, the ratio |R ₁₁/R₁₂| increased. The polar nanoregions found in K _0.95Na_0.05Ta_1-xNb_xO₃ crystals near the Curie temperature are believed to be responsible for this effect. A phenomenological model is proposed to analyze the impact of these polar nanoregions on the quadratic electro-optic effect.
