Metasurface Holography on a Relative-Phase Manifold for Stable and High Fidelity Tweezer-Array Generation
Yichen Zhu, Zifeng Li, Xiaopeng Li +4
We present a new holographic approach for generating large scale, polarization resolved optical tweezer arrays. By analyzing the ideal Jones fields that realize a target pattern, w…
Sculpting Topological Modes on Photonic Chips by Artificial Gauge Fields
Zhiyuan Lin, Jian Li, Wange Song +7
Significant efforts have been devoted to manipulating topological states, which often manifest as localized modes at interfaces between distinct topological phases. In this work, w…
High-order virtual gain for optical loss compensation in plasmonic metamaterials
Fuxin Guan, Zemeng Lin, Sixin Chen +2
Metamaterials exhibit extraordinary properties yet suffer from pronounced wave dissipation, particularly in optical imaging and sensing systems. Recent advances leveraging complex…
Bound-extended mode transition in type-II synthetic photonic Weyl heterostructures
Wange Song, Zhiyuan Lin, Jitao Ji +7
Photonic structures with Weyl points (WPs), including type-I and type-II, promise nontrivial surface modes and intriguing light manipulations for their three-dimensional topologica…
Observation of topology transition in Floquet non-Hermitian skin effects in silicon photonics
Zhiyuan Lin, Wange Song, Li-Wei Wang +7
Non-Hermitian physics has greatly enriched our understanding of nonequilibrium phenomena and uncovered novel effects such as the non-Hermitian skin effect (NHSE) that has profoundl…
