Quasi‐BIC and Reflective Mode Coupling Drives SHG Beyond the Q Factor Limit

open access: yesSmall, EarlyView.
An analytical expression is developed to relate second‐harmonic generation to both the resonance Q factor and absorptance. Simulations and experiments on a dual‐resonance 3R‐MoS2 metasurface validate the formula, showing that absorptance engineering provides an effective route to enhance SHG beyond conventional Q‐only design.
