Fig. 3. （a） Schematic diagram of the simulated propagation path along the z-axis when m=2 and n=2. The blue dashed box represents its corresponding light field intensity distribution diagram. （b）：n=0， （c）：n=1， （d）：n=2. For groups （b）， （c）， and （d）， from top to bottom， m is 2， 1， 0 in sequence. From left to right， they represent the phase diagram and the light field intensity distribution diagrams at propagation distances of -200， 0， and 200 respectively
