• Both the second-order nonlinear distribution and the built-in electric field have been measured in poled Infrasil™ silica samples, leading to the determination of the third-order nonlinear susceptibility spatial distribution. A difference between the χ(2) and electric field profiles has been observed in the first micrometers near the surface in contact with the anode. This behavior could be attributed to a modification of the χ(3) susceptibility in the poled region.
