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…
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…
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…
Experimental Realization of a Reflections-Free Compact Delay Line Based on a Photonic Topological Insulator
Kueifu Lai, Tzuhsuan Ma, Xiao Bo +2
Electromagnetic (EM) waves propagating through an inhomogeneous medium inevitably scatter whenever electromagnetic properties of the medium change on the scale of a single waveleng…
Experimental Demonstration of Phase Modulation and Motion Sensing Using Graphene-Integrated Metasurfaces
Nima Dabidian, Shourya Dutta-Gupta, Iskandar Kholmanov +8
Plasmonic metasurfaces are able to modify the wavefront by altering the light intensity, phase and polarization state. Active plasmonic metasurfaces would allow dynamic modulation…
