Fabrication of Spiral Phase Plate Using Photoresist for OAM Generation

Not Accessible

Your library or personal account may give you access

Abstract

An effective spiral phase plate (SPP) is fabricated using photoresist for OAM generation. The height of SPP is linearly proportional to the angle, which can achieve OAM generation with high purity up to 98.8%.
