Vector Beam Generation with a SLM and a Common-Path Interferometer

Cylindrical vector beams are found to be of help in different applications. In this example, following the work of X.-L. Wang, et al. in Opt. Lett. 32, 3549-3551 (2007), we build up a common-path interferometric setup. It consists of SLM, apertures, quarter-waveplates, grating combiner, and lenses in a 4f setup. Using this setup, we simulate the generation of cylindrical vector beams. By changing selected parameters for the amplitude transmission loaded on the SLM, we compare the difference in the results as well.
