Abstract

We report the fabrication of low-loss single-mode waveguides in the near- and mid-infrared in gallium lanthanum sulfide using femtosecond lasers. Three different techniques were explored: cumulative heating, slit-beam shaping and multiscan. Low propagation losses of 1.82 ± 0.07 dB/cm at 1550 nm were achieved.
