Nonreciprocal subdiffraction imaging with staggered gyromagnetic photonic crystals
Rui Ding, Tianshu Zhang, Jiarui Yu +4
Subdiffraction imaging serves as a novel technique to enhance the optical imaging resolution, where a backscattering-free approach remains so far unavailable. Here, we theoreticall…
Fragility of Unidirectional Transport in Weakly Disordered Photonic Chern Insulators
Xiaoxuan Shi, Tiantao Qu, Xianbin Wu +3
Photonic Chern insulators enable unidirectional light transport protected by nontrivial band topology -- essential for robust photonic integrated circuits and error-free communicat…
Band alignment effect in the topological photonic alloy
Tiantao Qu, Mudi Wang, Jun Chen +1
Recently, a photonic alloy with non-trivial topological properties has been proposed, based on the random mixing of Yttrium Iron Garnet (YIG) and magnetized YIG rods. When the dopi…
Bulk-spatiotemporal vortex correspondence in gyromagnetic double-zero-index media
Ruo-Yang Zhang, Xiaohan Cui, Yuan-Song Zeng +8
Photonic double-zero-index media, distinguished by concurrently zero-valued permittivity and permeability, exhibit extraordinary properties not found in nature. Remarkably, the not…
Three-dimensional non-reciprocal transport in photonic topological heterostructure of arbitrary shape
Mudi Wang, Ruo-Yang Zhang, Chenyu Zhang +6
Electromagnetic wave propagation in three-dimensional space typically suffers omnidirectional scattering when encountering obstacles. In this study, we employed Chern vectors to co…
Experimental demonstration of non-adjacent band topology connecting multiple nodal links
Dongyang Wang, Biao Yang, Mudi Wang +5
Nodal links are special configurations of band degeneracies in the momentum space, where nodal line branches encircle each other. In PT symmetric systems, nodal lines can be topolo…
Topological one-way large-area waveguide states in magnetic photonic crystals
Mudi Wang, Ruo-Yang Zhang, Lei Zhang +4
We have theoretically and experimentally achieved large-area one-way transport by using heterostructures consisting of a domain of an ordinary photonic crystal (PC) sandwiched betw…
