Abstract :
For the first time, an observation of second-order nonlinear susceptibility in an As2S3 chalcogenide glass thin film is reported. Both thermal poling and optical poling were used to induce this nonlinearity. In both cases, the magnitude of the χ333 coefficient was estimated to be >0.6 pm/V
