| Abstract: | Spiral phase plate (SPP) can be used to generate orbital-angular-momentum (OAM) light beams which have great applications in optical manipulation, quantum information and so on. In this paper, we developed an economical method for fabricating SPP by employing the printed Continuous Gray-scale Mask (CGM). The design approach and photolithography progress are discussed in detail. As the results, a practical SPP with topological charge L=3 is fabricated and tested by optical surface profile (Counter GT) and Mach-Zehnder interferometer. Our results show a low-cost and high efficiency processing method to fabricate high quality SPP. |
