Liang Fang, Peilin Liu, Jiayi Zhang, Jinman Chen, Qinjun Chen, Chujun Zhao, Liang Fang
2025-10-03 ChinaXiv: chinaxiv-202510.00027 Original EN

We report an intriguing Poynting vortex street produced by 3D vectorial superposition of two counterpropagating modes in different mode orders on silicon-based waveguides. Importantly, this Poynting vortex street can produce composite topological textures characterized by spin skyrmion (bimeron) arr…

Ultra-high resolution and large range on-chip Fano-enhanced thermometer based on spectral analysis
