Enhanced terahertz third-harmonic generation by bound states in the continuum in graphene grating-like metamaterial

open access: yesFrontiers in Physics, 2023
Non-linear metamaterials hold great promise for enhanced terahertz harmonic generation. Here, we numerically investigate enhanced terahertz third-harmonic generation (THG) by exploiting the symmetry-protected bound states in the continuum (BICs) in ...

Bound states in the continuum (BIC) accompanied by avoided crossings in leaky-mode photonic lattices

open access: yesNanophotonics, 2020
When two nonorthogonal resonances are coupled to the same radiation channel, avoided crossing arises and a bound state in the continuum (BIC) appears with appropriate conditions in parametric space. This paper presents numerical and analytical results on
