Abstract

The authors report what is, to their knowledge, the highest electro-optic effect measured in a germanosilicate fibre ever reported. The electro-optic effect based on a permanent second- order nonlinearity has been induced by UV-excited poling at 193 nm with an electric field > 8 × 10⁵ V/cm. Polarisation dependence of the V_πL product in a birefringent fibre has been observed, and the lowest V_πL product obtained for the TE mode of 32Vcm, comparable to that based on r₂₂ of LiNbO₃, has been, measured at 633nm with a phase modulation at frequencies up to 5 MHz.
