Abstract

We numerically study photo-induced waveguides using a single Bessel beam in a photorefractive (PR) medium. Under self-focusing nonlinearity, we demonstrate the possibility for creating complex waveguiding structures with multiple inputs/outputs channels. The truncation of the incoming Bessel beam, the nonlinearity of the PR medium, the light intensity, the order and the size of the Bessel beam are the key parameters for achieving different configurations with high guiding efficiencies. As such not only classical X or Y couplers but also more complex structures can be generated with up to 7 identified inputs/outputs. These results provide large opportunities for all-optical interconnects.
