Optimizing DMD-based vector beam generation for increased utility

Structuring the fundamental degrees of freedom of optical beams has exploded as a research area in recent years. DMDs have become a common method to generate these fields. In this work, we address some remaining hurdles to reducing the size, complexity and ease of use of systems able to generate vector beams (beams with inhomogeneous polarization). We analyse some of the design considerations for higher efficiency and remove crosstalk to increase the possible complexity of the beams produced. An increase in the azimuthal index of Laguerre-Gaussian modes from 4 to 15 has been observed. Finally, we built a feedback system to get the resolution of alignment and realignment to sub-300 microns. These improvements and techniques aid in improved dissemination in application areas outside of physics and optics such as chemistry, microscopy, communication and optical characterisation.
