Optical channel waveguide in chalcogenide (Ga:La:S) glass

A.K.Mairaj, A.Fu, H.N.Rutt and D.W.Hewak


We report on a novel method for fabricating optical channel waveguides in Ga:La:S chalcogenide glass, through continuous wave direct UV laser writing (λ=244nm). Well-formed single mode channel structures, with low propagation losses of 0.38±0.05 dB/cm at 1.3μm were engineered through this technique.
