The observation of discrete spatial solitons in fs laser written waveguide arrays in fused silica is reported for the .rst time. The fs writing process permits the speci.c setting of the linear and nonlinear guiding properties of the waveguides. The results in this paper reveal a new avenue for the fabrication of various nonlinear optical devices.
