    "abstract": "We demonstrate that nonlinear directional coupler with special bending of\nwaveguide axes can be used for all-optical switching of polychromatic light\nwith very broad spectrum covering all visible region. The bandwidth of\nsuggested device is enhanced five times compared to conventional couplers. Our\nresults suggest novel opportunities for creation of all-optical logical gates\nand switches for polychromatic light with white-light and super-continuum\nspectrum.",
