Ultrafast Laser Inscription of High-Performance Mid-Infrared Waveguides in Chalcogenide Glass

Résumé

We present the realization of mid-infrared waveguide by ultrafast laser inscription technique in a chalco-genide glass. Our approach is based on multicore waveguide that consists in an alignment on a mesh of positive refractive index channels placed parallel to each other. Two different meshes are investigated with different refractive index contrasts between the channel and the glass matrix. A detailed analysis of the performances at a wavelength of 4.5 mu m shows propagation losses of 0.20 +/- 0.05 dB/cm and coupling efficiencies higher than 60%.
