Abstract
A large linear electrooptic phase shift observed in a germanosilicate fiber has been induced by thermal poling at about 250 °C for 20-60 min with an electric field of >8 x 105 V/cm and a 3.3-cm electrode length. Polarization dependence of the V×L product in a birefringent germanosilicate fiber has been found, and the lowest V×L product has been measured for TE-polarization of 224 V/cm at 633 nm, Furthermore, it has been found that the electrical resistance between the electrodes is reduced by thermal poling.
