Abstract

The largest second harmonic generation (SHG) coefficient measured in a ultraviolet (UV)-poled Ge:SiO2 glass is reported. The UV-excited poling in a Ge:SiO2 glass fabricated by the vapor phase axial deposition (VAD) method was performed with an electric field up to 3×105 V/cm. The induced coefficient was determined by measuring SHG in UV-poled Ge:SiO2 glasses using the Maker-fringe technique. An anisotropic refractive index change caused by the UV-poling is an evidence of breaking the inversion symmetry in glass.
