Abstract : We present a new procedure for direct laser writing of high performance waveguides in chalcogenide glass. The propagation losses are measured to be lower than 0.2 dB/cm both in the near- (λ = 155 μm) and in the mid-infrared (λ = 45 μm). © 2018 The Author(s).
Keywords : Propagation loss Infrared devices Midinfrared Direct laser writing Chalcogenide glass Waveguides Photonics Nanophotonics
