Paper Abstract

We describe interferometric measurements of the DC Kerr susceptibilities in an SiO2-GeO2 channel waveguide. The measured magnitude of (chi) 1111(3)(-(omega) ; (omega) , 0,0) equals 2.44 +/- 0.2 X 10-22 m2/V2 is comparable to the previously measured optical Kerr susceptibility. However, the ratio of nonlinear tensor elements (chi) 1111(3)/(chi) 1122(3) equals 1.1 for the DC Kerr effect differs from that observed in the optical Kerr effect where (chi) 1111(3)/(chi) 1122(3) equals 3. We provide theoretical interpretation for this difference in the polarization dependence.
