Multi-mode resonance of bound states in the continuum in dielectric metasurfaces
Bound states in the continuum (BIC) represent distinct non-radiative states endowed with infinite lifetime and vanishing resonance linewidth. Introducing asymmetric perturbation to the system can convert true BICs into h…

Large-area silicon photonic crystal supporting bound states in the continuum and optical sensing formed by nanoimprint lithography
Optical bound states in the continuum (BIC) are found in various dielectric, plasmonic and hybrid photonic systems. The localized BIC modes and quasi-BIC resonances can result in a large near-field enhancement and a high…
