Abstract

Space-variant Pancharatnam–Berry phase optical elements based on computer-generated subwavelength gratings are presented. By continuously controlling the local orientation and period of the grating we can achieve any desired phase element. We present a theoretical analysis and experimentally demonstrate a Pancharatnam–Berry phase-based diffraction grating for laser radiation at a wavelength of $10.6 \mathit{\mu }\mathrm{m}$.
