We investigate the properties of the families of spatial walking solitons propagating in planar waveguides made of quadratic nonlinear media under conditions for second-harmonic generation in the presence of Poynting vector walk-off. We study in detail the shape and various features of the solitons, their stability on propagation, and their excitation.
