摘　　要：The fundamental concepts in condensed matter physics introduced to topological photonics inspire the rapid development of photonic topological states[1–3].The chiral edge states of topological insulators unidirectionally propagate along boundaries and require the breaking of time-reversal symmetry[4–9].The degenerate clockwise and counterclockwise modes of ring resonators experience opposite artificial magnetic fields and provide a pseudospin degree of freedom[6].The helical edge states of timereversal symmetric topological insulators with different pseudospins unidirectionally propagate in opposite directions.
