Photonic biosensing via Su-Schrieffer-Heeger boundary modes
Yang Liu, Jian-Hua Jiang
We propose a conceptual device for multiplexed biosensor in a photonic crystal chip based on the Su-Schrieffer-Heeger mechanism. Remarkably, the proposed biosensor can identify thr…
Higher-order topological phases in bilayer phononic crystals and topological bound states in the continuum
Xiao-Yu Liu, Yang Liu, Zhan Xiong +2
Recent studies on the interplay between band topology and layer degree of freedom provide an effective way to realize exotic topological phases. Here we systematically study the $C…
