Paper Abstract

We present a novel type of diffractive optical elements - a nonlinear spiral phase plate whose transmission function is described as exp(iφmn). The light field generated by the element has a spiral-shaped intensity and phase distribution, a non-uniform orbital angular momentum (OAM) distribution and spiral-shaped energy flow. Because of the non-linear azimuthal phase variation, the nonlinear spiral phase plates demonstrate angle-dependent distortion resistance properties. We believe that the proposed nonlinear spiral phase plates will be useful for the realization of OAM-Mode Division Multiplexing in optical communication systems as well as in the area of laser manipulation and laser-matter interaction for fabrication of unique chiral metasurfaces that can be used in optical communication systems too.
