    "abstract": "We propose a novel chirped structure consisting of a low index polymer core\nbounded by modulated multilayer claddings, to realize an optical field\nconcentrator with virtually zero propagation losses in a wide spectral range,\nindependent of wave polarization. In spite of the absence of the total internal\nreflection mechanism, properly designed multilayer claddings ensure the\nachievement of unitary transmittance in a wide spectral range, including the\nwidely used wavelengths for optical communications. Several cladding geometries\nobtained by varying the thicknesses of the cladding layers are reported and\ndiscussed.",
