Paper Abstract

The curved fringes that exist in spherical diffractive lenses present problems in terms of the computational cost of fracturing the curved fringes into e-beam acceptable shapes, and the fact that the resulting minimum fringe width is limited to several ebeam spot widths. Using orthogonal cylindrical diffractive lenses (OCDL), both of these problems can be overcome because the e-beam data is made up entirely of rectangles. OCDLs also allow different focal lengths in the X and Y directions for new applications. The design and fabrication of OCDLs is presented, along with experimental results.
