Unidirectional bound states in the continuum in Weyl semimetal nanostructures
文献摘要：
Recently studied bound states in the continuum(BICs)enable perfect localization of light and enhance light-matter interactions although systems are optically open.They have found applications in numerous areas,including optical nonlinearity,light emitters,and nano-sensors.However,their unidirectional nature in nonre-ciprocal devices is still elusive because such trapping states are easily destroyed when the symmetry of an optical system is broken.Herein,we propose nonreciprocal and dynamically tunable BICs for unidirectional confine-ment of light and symmetry-protected BICs at Γ-point by introducing antiparallel magnetism into the optical system.We demonstrate that such BICs can be achieved by using topological magnetic Weyl semimetals near zero-index frequency without any structural asymmetry,and are largely tunable via modifying the Fermi level.Our results reveal a regime of extreme light manipulation and interaction with emerging quantum materials for various practical applications.
