By means of computer simulation, we demonstrate the possibility of formation of a new type of surface solitons in nonlinear layered structures. The initial soliton is located inside a photonic crystal and occupies several of its layers. Its profile can be found from the solution to the eigenvalue problem for a nonlinear Schrodinger equation with periodic linear and nonlinear coefficients. Surface solitons are formed as a result of perturbation of the wave vector, which leads to soliton motion across photonic crystal layers. After several reflections from the side boundaries of the crystal, under certain conditions, the soliton becomes attached to the side boundary. A characteristic feature of the discussed soliton is the fact that its penetration depth into the photonic crystal medium is equal to the thickness of several crystal layers.
