Tolerance to Lateral Displacement and Angular Deflection on Mode Sorting Performance for Beams Carrying Orbital Angular Momentum

摘要

We numerically investigate the tolerance to lateral displacement and angular deflection on the mode sorting performances for beams carrying orbital angular momentum. Comparing Laguerre-Gaussian beams and perfect vortex beams in terms of crosstalk on the sorting result reveals that Laguerre-Gaussian beams show stronger tolerance.
