Sensitive sucrose biosensors with high Q factors empowered by quasi-bound states in the continuum in compound grating waveguide structures
As a special kind of localized states, bound states in the continuum (BICs) have been widely utilized to design high-performance lasers, absorbers, and biosensors. In this paper, we realize a BIC in a compound grating waveguide structure based on the switchable guided resonance. Empowered by the ult...
