Bound States in the Continuum in Asymmetric Dielectric Metasurfaces (Laser Photonics Rev. 17(3)/2023)

Resonant Metasurface In article number 2200564, Lujun Huang, Guanhai Li, Andrey E. Miroshnichenko, and colleagues demonstrate accidental bound states in the continuum (BIC)s at Γ-point in an asymmetric dielectric metasurface. The measured Q-factor is up to 4.99 × 103. This work may enrich the library of BICs and find exciting applications in developing high-performance photonics devices, such as nanolasers, biosensors, etc.
