Abstract
A novel method for fabricating optical channel waveguides in Ga:La:S chalcogenide glass, through continuous wave direct UV laser writing (λ = 244 nm) is reported. Well-formed singlemode channel structures, with low propagation losses of 0.38 ± 0.05 dB/cm at 1.3 µm, were engineered using this technique.Keywords
