Spin-1 conical diffraction at a nexus point

Caption

a, Schematic of spin-1 conical diffraction for a monochromatic beam with frequency at NP incident on the PhC along the z-axis. The hollow cone illustrates the envelope of the trajectories corresponding to the wave components on the two conical iso-frequency surfaces around the NP. The straight light beam in the PhC corresponds to the wave components on the flat iso-frequency surface. Simulated b intensity and c phase (average of each period in the x direction) distribution of different output spin components (column indices) on the horizontal xy plane
