An optimized fractional fractal photon sieve with two optimum ratios and optimized apodization window values
An optimized fractional fractal photon sieve (OFFPS) is proposed to generate the tailorable first-order main focus with many subsidiary foci and the low-intensity higher-order diffraction foci. The OFFPSs have enlarged minimum pinhole sizes and can be fabricated easily. In addition, the OFFPS can pr...

| description | An optimized fractional fractal photon sieve (OFFPS) is proposed to generate the tailorable first-order main focus with many subsidiary foci and the low-intensity higher-order diffraction foci. The OFFPSs have enlarged minimum pinhole sizes and can be fabricated easily. In addition, the OFFPS can produce the image with the low chromatic aberration at the arbitrary axial position. The OFFPS has two optimum ratios d/w of the sizes of the pinholes (d) to the underlying zone widths (w) for total and narrow zones, respectively. Moreover, fractional fractal photon sieves (FFPSs) with different fractional N and integral S may have the different first optimum ratios. In addition, the optimized apodization window values for the OFFPS can be used to enhance the main focal intensity. It will be proved in the simulations and experiments that the higher odd orders for the OFFPS are highly reduced. The proposed photon sieve can be used to trap particles stably, and produce images with low chromatic aberration or high-resolution hard-x-ray vortices. |
