Abstract:
We theoretically reveal that a two-dimensional magneto-optical photonic crystal shows two pairs of one-way edge Dirac cones, whereby only clockwise and anticlockwise circle wave scattering (facing the direction of external applied magnetic field) are allowed in the second and third band-gaps, respectively. These two different chiral pathways originate from the different exchange of Chern numbers, which are attributed to the broken time-reversal symmetry. Moreover, below and above the edge Dirac point, the edge modes show the left-handed (counter propagation of group velocity and phase velocity) and right-handed characters, respectively.
