Transport properties in the photonic super‐honeycomb lattice — a hybrid fermionic and bosonic system Academic Article uri icon

abstract

  • We report on the transport properties of the superhoneycomb lattice, the band structure of which possesses a flat band and Dirac cones, according to the tightbinding approximation. The superhoneycomb model combines the honeycomb lattice and the Lieb lattice and displays the properties of both. It also represents a hybrid fermionic and bosonic system, which is rarely seen in nature. By choosing the phases of input beams properly, the flatband mode of the superhoneycomb lattice will be excited and the input beams will exhibit strong localization during propagation. On the other hand, if the modes of Dirac cones of the superhoneycomb lattice are excited, one will observe conical diffraction. Furthermore, if the input beam is properly chosen to excite a sublattice of the superhoneycomb lattice and the modes of Dirac cones with different pseudospins, e.g., by the threebeam interference pattern, the pseudospinmediated vortices will be observed. image
