High order vortex beams generated directly from photonic-crystal surface-emitting laser with honeycomb lattice

We demonstrate that high order vortex beams are generated directly from honeycomb-lattice photonic crystal surface-emitting laser. The measured divergence angle is about 1 degree, and the far field pattern was proved to be superposition of RCP and LCP with topological charge ±2, respectively.
