• Owing to the remarkable properties of chalcogenide glasses, chalcogenide optical waveguides should play a significant role in the development of integrated optics. This work demonstrates that an optical waveguide can be obtained by a simple proton implantation in gallium lanthanum sulphide (GLS) glass. Two modes exist in the waveguide at a wavelength of 632.8 nm and the refractive index profile of the waveguide is reconstructed. The near-field pattern of the transmitted light is obtained, and the propagation loss is about 3.2 dB/cm for the present waveguide.
