摘要：

The structural and mechanical characteristics of ultrafast lasers inscribed Er2O3-doped GeGaS chalcogenide glass waveguides have been investigated with the aid of micro-Raman spectroscopy and nanoindentation. The mechanical property data indicates two distinct regions within the waveguides, with the top of the waveguide having considerably lower elastic modulus and hardness. Raman spectroscopy also confirms the existence of such distinct regions. These results are interpreted in terms of structural modifications made by the laser inscriptions to the glassy network.
