Topology-Enabled Switchable Unidirectional Radiative Band in a Bilayer Photonic Crystal
Zhiyi Yuan, Vytautas Valuckas, Yuhao Wang +6
Controlling how an open photonic system exchanges energy with its environment-and in particular how it radiates into the far field-is a cornerstone of non-Hermitian wave physics an…
Generalized Non-Hermitian Hamiltonian for Guided Resonances in Photonic Crystal Slabs
Viet Anh Nguyen, Hung Son Nguyen, Zhiyi Yuan +6
We develop a generalized non-Hermitian Hamiltonian formalism for guided resonances in photonic crystal slabs, derived directly from Maxwell's equations through a systematic guided-…
Hybridization of Non-Hermitian Topological Interface Modes
Yuhao Wang, Hai-Chau Nguyen, Zhiyi Yuan +5
We propose and experimentally demonstrate the hybridization of radiating topological interface states, analogous to Jackiw-Rebbi states but in gain media with radiation fields. Thi…
Unified Weak-to-Strong Coupling Transitions and Radiation Interference Induced by Vertical-Symmetry Breaking in Photonic Crystal Slabs
Huy Hoang Chu, Raphael Mermet-Lyaudoz, Florian Dubois +10
Vertical-symmetry breaking provides a versatile means of coupling leaky photonic-crystal resonances that are otherwise protected by opposite out-of-plane parity. Here, we develop a…
