The Mach–Zehnder interferometer contains a Dove prism in each arm where each has a mirror plane around which the transverse phase profile is inverted. The authors' consequence of the inversions is that the interferometer needs no alignment. Instead the interferometer defines a unique axis about which the input beam must be coupled. Experimental results are presented for the fringe contrast, reaching a maximum value of 93±1%.enInterferometersLight beamsLensesPrismsOpticsRobust interferometerLight beamsRobust interferometer for the routing of light beams carrying orbital angular momentumArticleLavery, M., Dudley, A.
