Mode-selective Single-dipole Excitation and Controlled Routing of Guided Waves in a Multi-mode Topological Waveguide
Yandong Li, Yang Yu, Kueifu Lai +4
Topology-linked binary degrees of freedom of guided waves have been used to expand the channel capacity of and to ensure robust transmission through photonic waveguides. However, s…
Topologically Protected Photonic Modes in Composite Quantum Hall/Quantum Spin Hall Waveguides
Shukai Ma, Bo Xiao, Yang Yu +3
Photonic topological systems, the electromagnetic analog of the topological materials in condensed matter physics, create many opportunities to design optical devices with novel pr…
Transition radiation in photonic topological crystals: quasi-resonant excitation of robust edge states by a moving charge
Yang Yu, Kueifu Lai, Jiahang Shao +7
We demonstrate, theoretically and experimentally, that a traveling electric charge passing from one photonic crystal into another generates edge waves -- electromagnetic modes with…
Sorting and Routing Topologically Protected Edge States by their Valleys
Kueifu Lai, Yang Yu, Yuchen Han +3
We experimentally demonstrate and characterize a photonic platform containing heterogeneous topological phases. This platform is shown to support valley-spin locked edge states tha…
Topologically-protected refraction of robust kink states in valley photonic crystals
Fei Gao, Haoran Xue, Zhaoju Yang +6
Recently discovered valley photonic crystals (VPCs) mimic many of the unusual properties of two-dimensional gapped valleytronic materials such as bilayer graphene or MoS2. Of the u…
Exciting Reflectionless Unidirectional Edge Modes in a Reciprocal Photonic Topological Insulator Medium
Bo Xiao, Kueifu Lai, Yang Yu +3
Photonic topological insulators are an interesting class of materials whose photonic band structure can have a bandgap in the bulk while supporting topologically protected unidirec…
