title: Fabrication and characterization of low loss rib chalcogenide waveguides made by dry etching.
abstract: We report the fabrication and characterization of rib chalcogenide waveguides produced by dry etching with CF4 and O2. The high index contrast waveguides (Deltan ~1) show a minimum propagation loss of 0.25 dB/cm. The high refractive nonlinearity of 100 times silica in As2S3 allowed observation of a pi phase shift due to self-phase modulation of an 8 ps duration 1573 nm pulse in a 5 cm long waveguide.
