By launching a counter-propagating copolarized probe we assess the guided-wave behavior induced by the solitons and demonstrate a novel all-optical switch. Varying soliton power the probe gets trapped into one or two or three guided-waves by the soliton-induced index perturbation, an effect supported by the nonlocal nonlinearity.We acknowledge support from the Australian Research Council.© 2012 Optical Society of AmericaKeywords: All optical switch; All-optical switching; Co-polarized; Counterpropagating; Nematicons; Nonlocal nonlinearities; Spatial solitons; Guided electromagnetic wave propagation; Nematic liquid crystals; Optical switches; Probes; Solitons2012-10-2210.1364/OE.20.0247012016-06-14
