  • Abstract
    We demonstrate orbital angular momentum modes separation using a geometrical transform-based mode sorter combined with a spatial Fast Fourier Transform. The observed crosstalk between the adjacent modes is <;-11.8 dB. A lower crosstalk of <;-18.6 dB is anticipated by simulation results.
