Abstract

A novel subwavelength focusing using an nanohole patterned structure or nano-photon sieves(NPS) is proposed. By employing a nanohole array instead of the ring pattern in conventional Fresnel micro-zone-plate(FMZP) and incorporating a Gaussian modulation function on the density of the nanohole array, it is found that the side lobes of the NPS can be effectively suppressed compared with that of FMZP and both the intensity distribution of focal spot and the side-lobes of focal spot exhibit better symmetric behavior than that of the FMZP. The intensity of electric field at the focal plane can be further improved by introducing a multi-layer system with a dielectric transition layer(i.e. NaF).
