Paper Abstract

We derive analytical expressions containing a hypergeometric function to describe the Fresnel and Fraunhofer diffraction of a plane wave of circular and ring-like cross-section by a spiral phase plate (SPP) of an arbitrary integer order. Experimental diffraction patterns generated by an SPP fabricated in resist through direct e-beam writing are in good agreement with the theoretical intensity distribution. We discuss experiments on manipulation of a group of microspheres in light beams with angular harmonics generated by diffractive optical elements.
