High second-order nonlinear susceptibility induced in chalcogenide glasses by thermal poling.
High second-order susceptibility has been created in a chalcogenide glass from Ge-Sb-S system. A thermal poling process was used to produce this non-linear effect and a second harmonic generation experiment allowed characterizing the phenomenon. A maximum chi(2) value of 8.0+/-0.5 pm/V was measured for the first time to our best knowledge in sulfide glasses.
