Significant enhancement of magneto-optical effect in one-dimensional photonic crystals with magnetized epsilon-near-zero defect
Zhiwei Guo, Feng Wu, Chunhua Xue +4
Nonreciprocal (NOR) transmission with magneto-optical materials plays a critical role in a broad range of applications, such as optical isolation, all-optical signal processing, an…
Actively controlling the topological transition of dispersion based on electrically controllable metamaterials
Zhiwei Guo, Haitao Jiang, Yong Sun +2
Topological transition of the iso-frequency contour (IFC) from a closed ellipsoid to an open hyperboloid, will provide unique capabilities for controlling the propagation of light.…
Zak phase and band inversion in dimerized one-dimensional locally resonant metamaterials
Weiwei Zhu, Ya-qiong Ding, Jie Ren +4
Zak phase, which refers to the Berry's phase picked up by a particle moving across the Brillouin zone, characterizes the topological properties of Bloch bands in one-dimensional pe…
Experimental demonstration of the robust end state in a split-ring-resonator chain
Jun Jiang, Zhiwei Guo, Ya-qiong Ding +4
One of the fascinating topological phenomena is the end state in one dimensional system. In this work, the topological photonics in the dimer chains composed by the split ring reso…
