Paper Abstract

This work presents the design and fabrication of diffractive optical elements for use in optical communication systems. The device geometry uses a vortex pattern to impart orbital angular momentum (OAM) onto an incident beam, providing a robust method for transmitting information through free space. Two refractive elements were designed and fabricated to use log-polar coordinate transformation of an incident OAM beam at 1550 nm for communications systems. Furthermore, diffractive elements were designed based on the phase profile of this refractive element. Fabrication of the devices uses conventional photolithography on a fused silica substrate.
