Abstract
Bound states in the continuum (BICs) are radiationless localized states embedded in the part of the parameter space that otherwise corresponds to radiative modes. Many decades after their original prediction(1-3) and early observations in acoustic systems(4), such states have been demonstrated recently in photonic structures with engineered geometries(5-18). Here, we put forward a mechanism, based on waveguiding structures that contain anisotropic birefringent materials, that affords the existen...
