Material-Anisotropy-Driven Topological Optical Lattices on Thin-Film Lithium Niobate
Siyuan Zhang, Baoqi Shi, Lei Gui +7
Integrated structured-light sources usually obtain high-dimensional orbital angular momentum (OAM) states by encoding each channel into separate gratings, waveguides or metasurface…
Kramers-Kronig causality in integrated photonics: The spectral tension between ultraviolet transition and mid-infrared absorption
Yue Hu, Zhenyuan Shang, Chenxi Zhang +12
Dispersion engineering via geometric confinement is essential to integrated photonics, enabling phenomena such as soliton microcombs, supercontinua, parametric oscillators, and ent…
Enhancement of vacuum-ultraviolet dispersive-wave emission using gas-filled tapered hollow-core fibers
Yinuo Zhao, Donghan Liu, Baoqi Shi +12
The recent breakthroughs in laser-driving 229Th nuclear transition have created an urgent demand for coherent vacuum-ultraviolet (VUV) sources delivering high spectral brightness a…
Metrology-grade mid-infrared spectroscopy for multi-dimensional perception
Baoqi Shi, Chenxi Zhang, Ming-Yang Zheng +11
The mid-infrared spectral window is essential for molecular fingerprinting and atmospheric sensing, yet unlocking its full potential is currently constrained by a fundamental instr…
