    "abstract": "A novel focusing structure with fractal properties is presented. It is a\nphoton sieve in which the pinholes are appropriately distributed over the zones\nof a fractal zone plate. The focusing properties of the fractal photon sieve\nare analyzed. The good performance of our proposal is demonstrated\nexperimentally with a series of images obtained under white light illumination.\nIt is shown that compared with a conventional photon sieve, the fractal photon\nsieve exhibits an extended depth of field and a reduced chromatic aberration.",
