Paper Abstract

Maker fringes measurements performed with hemispherical lenses pressed against a planar sample permit the propagation of light at very high internal propagation angle, and therefore the observation of many more fringes. The thickness of the active nonlinear region can be determined with accuracy. Results from optical measurements are compared to what is predicted by a charge migration model and by observed currents to the electrodes during poling. This comparison is relevant to the identification of the origin of second-order nonlinearities in silica glasses.
