abstract = {We propose to take advantage of the potential of self-trapped beams in photorefractive materials. This technique is very attractive as regards both the employed wavelengths and the possibility of obtaining an all-optical dynamical reconfigurability of the induced guiding structures. We will report on experimental demonstrations of self-induced photonic components using nonlinear beam interaction in photorefractive crystals. First we demonstrate collisions between two copropagating parallel coherent beams inside the photorefractive semiconductor iron doped Indium Phosphide (InP:Fe) at \λ = 1064 nm for optical routing applications. In a second time we focus on the interactions between two counter- propagating solitons in InP:Fe to automatically couple for instance a laser beam to an optical fiber.}
