Abstract
Kerr spatial solitons are observed in slab chalcogenide waveguides at near-IR wavelengths. Waveguides are realized either by electron-beam evaporation or rf sputtering of a Ge–Sb–S compound deposited on oxidized silicon wafer. The Kerr coefficient of the thin film is evaluated to be from the experimentally required soliton power at . Limitations due to material photosensitivity are revealed.
