Multi-channel waveguides induced by Bessel beams in a photorefractive medium
Résumé
We numerically investigate the propagation and interaction of Bessel beams in a photorefractive (PR) nonlinear medium. By varying Bessel beam parameters and the PR nonlinearity, complex multi-channel structures can be photoinduced by single or two counter-propagating (CP) Bessel beams. These results pave the way towards all-optical interconnects.
