Near-infrared demonstration of computer-generated holograms implemented by using subwavelength gratings with space-variant orientation

Abstract

We provide an experimental demonstration of novel form-birefringent computer-generated holograms at wavelengths of 1.55 and $10.6\mu \mathrm{m}$. These novel devices utilize a 2-D array of cells that can be fabricated with a single lithographic step. Each cell contains a subwavelength binary grating whose orientation controls the desired continuous phase profile within the cell.
