Experimental setup. a Scheme for optical wave propagation in a photorefractive slab waveguide embedded in a KLTN cystal. b Output image of the linear transmission through the sample and corresponding refractive index profile (see Methods). c Examples of the detected intensity in linear conditions for distinct realizations of the experiment showing different realizations of the disorder in the slab along x. Scale bars are 50 μm
