Abstract

The authors demonstrate a mechanism for focusing at optical frequencies based on the use of nanohole quasiperiodic arrays in metal screens. Using coherent illumination at 660 nm and scanning aperture optical microscopy, similar to 290 nm "hot spots" were observed at a distance of similar to 12.5 mu m from the array. Even smaller hot spots of about similar to 200 nm in waist were observed closer to the plane of the array.(c) 2007 American Institute of Physics.
