Description
Summary:Chalcogenide glass (ChG) waveguides with sub-micrometer widths are fabricated by a hot melt smoothing and micro-trench filling method using As2S7 glass and their properties on nonlinear optics are investigated. The third-order nonlinear optical property is measured by the experiment of stimulated four-wave mixing, showing a nonlinear coefficient of 14.1 W−1m−1. Stimulated Brillouin scattering amplification is also demonstrated in the waveguide sample. The measured Brillouin shift and Brillouin gain coefficient are 6.25 GHz and 377 W−1 m−1, respectively. The experiment results show that the ChG waveguides fabricated by this method have high quality and good performance on optical nonlinearity.
