Description
Based on the Cantor function and phase modulation, a tunable fractal axicon is formed on a liquid crystal on silicon (LCoS) with an improved generating method. It has higher focusing efficiency in higher fractal stage and approaches to 100% theoretically The on-axis intensity keeps its fractal structure unchanged in operation of fractal stages. The tunability of the axicon is demonstrated by tune fractal stage from 1 to 3 and focal length from 0.8m to 1 m. We also provide details of theoretical analyses and experimental results
