Abstract

We describe a simple, reliable, and reproducible fabrication technique for a high-order spiral phase plate with high power efficiency 86%. The performance of the fabricated Spiral Phase Plate (SPP) is verified by using vortex characteristics of fraunhofer and fresnel diffractions of a finite-radius plane wave, which is in agreement with the theoretical calculation result.
