| Performance of the system in straight-through and selective-blocking cases when multi-TAM states are incident. (a) Experimental results for incident beams; (b) TAM spectra of the output beams in the above two cases. The output patterns are consistent with the inputs at the straight-through cases. For the selective-blocking cases, the spatial filter placed at the separation plane is presented as Sp2. After blocking, the patterns of these beams convert from a petaloid shape into a doughnut shape. Credit: Li et al., doi 10.1117/1.AP.5.5.056002 |
