Abstract

Geometrical phases such as Pancharatnam and Berry phase, have been playing important role in classical wave and quantum physics. In topological photonics, the geometrical phases can be controlled with artificial gauge fields by designing lattice geometry of photonic crystals. Here, we theoretically and experimentally demonstrate that geometric phases can give rise to a new class of resonant states in topological ring resonators. Our simulations and analytical model reveal a hierarchy of the resonant modes and transformation of polarization states. Also, we provide experimental observations of the resonant states by infrared spectroscopy.
