Phys. Rev. Lett. 81, 3383–3386 (1998)Discrete Spatial Optical Solitons in Waveguide ArraysReceived 25 June 1998; published in the issue dated 19 October 1998 We report the observation of discrete spatial optical solitons in an array of 41 waveguides. Light was coupled to the central waveguide. At low power, the propagating field spreads as it couples to more waveguides. When sufficient power was injected, the field was localized close to the input waveguides and its distribution was successfully described by the discrete nonlinear Schrödinger equation. © 1998 The American Physical Society URL:
