Second harmonic generation from bound-state in the continuum-hosted few-layers van der Waals metasurface

Second harmonic generation from bound-state in the continuum-hosted few-layers van der Waals metasurface

Monolayer transition metals dichalcogenides (TMDs) have been coupled to bound-state in the continuum (BIC) hosted dielectric structures to attain high second harmonic generation (SHG). However, the transvers electric modes are strongly localized in the waveguides result in fairly weak exciton-photon...
