Strong resonance response with ultrahigh quality factor in grating-multilayer systems based on quasi-bound states in the continuum
Abstract Optical bound states in the continuum (BICs) exist in many photonic crystals and periodic structures with a strong resonance and ultrahigh Q factor. Such phenomena can be used in the designs of narrowband transmission filters, lasers, and sensors. In this paper, we consider the energy bands...
