Quasi-bound states in the continuum in finite waveguide grating couplers

Finite-size effects occurring for quasi-bound states in the continuum (qBICs) formed in symmetric and asymmetric all-dielectric waveguide grating couplers are investigated using numerical simulations for different configuration parameters. We find that the beam size plays a crucial role in the forma...
