Abstract :
As the formation of spatial optical solitons in photorefractive mediad is governed by modification of the refractive index, every single solitons in complex configurations of solitons can act as a single waveguide for other light beams. In this article, we demonstrate guiding of amplitude-modulated beams in complex configurations of photorefractive solitons carrying information; we analyze the received signal in the kilohertz frequency range. The possibility of data transmission combined with waveguide couplers opens the route to all-optical networks.
