Recovery of topologically robust merging bound states in the continuum in photonic structures with broken symmetry

Optical bound states in the continuum (BICs) provide a unique mechanism of light confinement that holds great potential for fundamental research and applications. Of particular interest are merging BICs realized in planar periodic structures by merging accidental and symmetry-protected BICs. Topolog...
