The resulting films are highly photosensitive and can be used without thermal annealing in waveguide fabrication. Waveguide losses as low as 0.2 dB/cm in laser written waveguides have been measured at 1550 nm. The results suggest that ultra-fast pulsed laser deposition may be an important process for the production of low loss waveguides in the chalcogenides.Keywords: Annealing; Arsenic compounds; Optical waveguides; Photosensitive glass; Ultrafast phenomena; Chalcogenide films; Pulsed laser deposition Chalcogenide glass films; Laser deposition; Optical waveguide200210.1016/S0169-4332(02)00375-62015-12-12
