Optical Characterization of Micro Spiral Phase Plates

Abstract

The results of our investigations on laser fabricated micro spiral phase plates in fused silica are presented. Other than in previous investigations we focussed on the optical characterization of the SPPs. As we could show, the laser-based process enables the generation of spiral phase plates with different topological charges, handedness, modulation depths and level numbers. Each geometric property influences the property of a transmitting electro-magnetic field and therefore the orbital angular momentum. For the optical characterization we observed and analysed the diffraction images of the generated SPPs. Moreover, we validated our results by calculating the diffraction patterns under variation of certain parameters.
