High-Efficiency Second-Harmonic Generation Using Quasi-Bound State in LiNbO<sub>3</sub> Metasurface

High-Efficiency Second-Harmonic Generation Using Quasi-Bound State in LiNbO<sub>3</sub> Metasurface

We numerically demonstrated a high-efficiency second-harmonic generation (SHG) using quasi-bound state in the continuum (quasi–BIC) in thin film LiNbO<sub>3</sub> (TFLN) metasurface. The TFLN possessed exceptionally high second-order nonlinear coefficients, contributing to the enhanced S...
