Modified Mach – Zehnder interferometer for determining the high-order topological charge of Laguerre – Gaussian vortex beams

This study demonstrates a self-referenced interferometric method to estimate the magnitude and sign of a high-order topological charge (TC) carried by incoming optical vortex beams. The proposed method uses a right-angle prism in a Mach – Zehnder interferometer setup with controlled lateral ...
