Abstract

We report the fabrication and characterization of rib chalcogenide waveguides produced by dry etching with CF₄ and O₂. The high index contrast waveguides (Δn ∼ 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 π phase shift due to self-phase modulation of an 8 ps duration 1573 nm pulse in a 5 cm long waveguide.
