Tunable high- Janus-to-chiral bound states in the continuum in bilayer PhCs
Zhexing Dong, Shengxuan Xia, Yee Sin Ang +1
We propose a bilayer all-dielectric PhC for controlling Janus bound states in the continuum (BIC) and optical chirality through symmetry-selective perturbations. Starting from a sy…
