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

Frontiers 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 ...

Chirped gratings in integrated optics [PDF]

, 1977
Gratings with variable periods (chirped gratings) have been fabricated by recording the interference pattern of a collimated laser beam with a converging beam generated by a cylindrical lens.

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

Nanophotonics, 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
