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…

Engineering of energy band and its impact on light transmission in non-reciprocal Hermitian hourglass lattice
Junhao Yang, Yuandan Wang, Yu Lin +3
We study a quasi-one-dimensional non-reciprocal Hermitian hourglass photonic lattice that can accomplish multiple functions. Under the effect of non-reciprocal coupling, this latti…
