Abstract
We apply the Rayleigh-Sommerfeld diffraction integral to solve the dif fracted fields of periodically phase-modulated apertures. We show that the diffraction of small phase modulated apertures (with few refracti ve index modulation periods) behaves as for phase gratings, but the sh arp diffraction peaks may already appear in the Fresnel region behind the aperture. Thus, these components may serve as lensless miniature i nterconnection gratings in micro-optics.
