Anomalous Light Scattering by Topological -symmetric Particle Arrays
C. W. Ling, Ka Hei Choi, T. C. Mok +2
Robust topological edge modes may evolve into complex-frequency modes when a physical system becomes non-Hermitian. We show that, while having negligible forward optical extinction…

Simultaneous Multi-frequency Topological Edge Modes between One-dimensional Photonic Crystals
Ka Hei Choi, C. W. Ling, K. F. Lee +2
We show theoretically that, in the limit of weak dispersion, one-dimensional (1D) binary centrosymmetric photonic crystals can support topological edge modes in all photonic band g…
