Original abstract

We demonstrate spectral and scattering properties of a photonic implementation of a modified Fano-Anderson model. The model includes formation of a symmetry-protected bound state in the continuum (BIC). We interpret the scattering spectra of the structures with the broken symmetry in terms of system eigenmodes. The Fano resonance associated with the excitation of quasi-BIC is explained as arising from the interference between this mode and another leaky mode.

Czech abstract

Popisujeme spektrální a rozptylové vlastnosti fotonické struktury, která je analogií rozšířeného Fanova-Andersonova modelu. Model zahrnuje vznik symetrií chráněných vázaných stavů v kontinuu. Fanova rezonance spojená s excitací kvazi-vázaného stavu v kontinuu byla vysvětlena jako důsledek interference mezi tímto modem a jiným "leaky" modem.
