Frequency tunable topological edge states of two-dimensional honeycomb lattice photonic crystals
Yuchen Peng, Bei Yan, Jianlan Xie +5
In this paper, the photonic quantum spin Hall effect (PQSHE) is realized in dielectric two-dimensional (2D) honeycomb lattice photonic crystal (PC) by stretching and shrinking the…
