Photonic Shankar skyrmion
Haiwen Wang, Shanhui Fan
We unveil a new topological quasiparticle of light in 3D space, named the photonic Shankar skyrmion. We show that an elliptically polarized field can be described by an SO(3) order…
Spatiotemporal steering of non-diffracting wavepackets
Haiwen Wang, Cheng Guo, Shanhui Fan
We study the dynamics of space-time non-diffracting wavepackets, commonly known as light bullets, in a spatiotemporally varying medium. We show that by spatiotemporal refraction, a…
Dynamic realization of emergent high-dimensional optical vortices
Dongha Kim, Geonhyeong Park, Yun-Seok Choi +9
The dimensionality of vortical structures has recently been extended beyond two dimensions, providing higher-order topological characteristics and robustness for high-capacity info…
Photonic torons, topological phase transition and tunable spin monopoles
Haijun Wu, Nilo Mata-Cervera, Haiwen Wang +3
Creation and control of topological complex excitations play crucial roles in both fundamental physics and modern information science. Torons are a sophisticated class of 3D chiral…
Metacrystals: Inversely-designed 3D-printed intelligent panels for 6G communications
Mohammad M. Asgari, Peter B. Catrysse, Shuai S. A. Yuan +3
Metasurfaces represent a promising platform for improving coverage in future communication systems. Passive designs are especially attractive because they need no power supply and…
Topological spin defects of light
Haiwen Wang, Charles C. Wojcik, Shanhui Fan
Topological defects are found in a variety of systems, and their existence are robust under perturbations due to their topological nature. Here we introduce a new type of topologic…
