    "abstract": "We report on the first experimental observation of discrete gap solitons in\nbinary arrays of optical waveguides. We observe the soliton generation when the\ninclination angle of an input beam is slightly above the Bragg angle, and show\nthat the propagation direction of the emerging gap soliton depends on the input\npower as a result of an inter-band momentum exchange.",
