So far, we have studied one-dimensional PT symmetric CROW structures, and have reported that the group velocity can be controlled more than 10 times. This time, we analyzed the propagation characteristic in the honeycomb lattice structure having two-dimensional PT symmetry. As a result, we have obtained that there is clear difference in the stability of the propagation, depending on its propagation direction.
