Abstract

A subwavelength concentric ring metal grating for visible light ( λ = 632.8 nm ) is designed and fabricated by electron-beam lithography to transform circularly polarized light into radially polarized light. Experimental results are compared to theoretical predictions and the advantages and disadvantages of the element with alternative methods are discussed.
