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…

Topological antilaser
Rui-Chang Shen, Chunquan Peng, Bingbing Wang +6
Coherent perfect absorption (CPA)-the time-reversed operation of lasing at threshold-relies on finely tuned interference and is intrinsically fragile to disorder and structural imp…

Topological modes in photonic waveguide arrays
Gang Jiang, Siyuan Zhang, Weiwei Zhu +2
Periodic driving is a powerful tool to generate exotic topological phases without static counterparts, such as the anomalous chiral edge modes from bulk bands with zero Chern numbe…
