Long-range coupling enabled multiband group-velocity control of topological edge states from slow light to light stopping
Junhao Yang, Jiarui Wang, Jingyu Liu +2
Topological edge states provide robust optical transport immune to disorder, yet their propagation velocity is usually constrained by the intrinsic band dispersion, limiting dynami…

Experimental realization of a full-band wave antireflection based on temporal taper metamaterials
Haonan Hou, Kai Peng, Yangkai Wang +5
As time can be introduced as an additional degree of freedom, temporal metamaterials nowadays open up new avenues for wave control and manipulation. Among these advancements, tempo…

Observation of wave amplification and temporal topological state in a genuine photonic time crystal
Jiang Xiong, Xudong Zhang, Longji Duan +6
Photonic time crystals (PTCs) are materials whose dielectric permittivity is periodically modulated in time, giving rise to bandgaps not in energy-as in conventional photonic cryst…
