Bound states in the continuum in subwavelength emitter arrays

Ordered lattices of emitters with subwavelength periodicities support unconventional forms of light-matter interactions arising from collective effects. Here, we propose the realization and control of subradiant optical states within the radiation continuum in two-dimensional lattices. We show how b...

description Ordered lattices of emitters with subwavelength periodicities support unconventional forms of light-matter interactions arising from collective effects. Here, we propose the realization and control of subradiant optical states within the radiation continuum in two-dimensional lattices. We show how bound states in the continuum (BICs) which are completely decoupled from radiative states emerge in non-Bravais lattices of emitters. Symmetry breaking results in quasi-BICs with greatly extended lifetimes, which can be exploited for quantum information storage. The analytical derivation of a generalized effective polarizability tensor allows us to study the optical response of these arrays. We discuss how thanks to the quasi-BICs, a rich phenomenology takes place in the reflectivity spectrum, with asymmetric Fano resonances and an electromagnetically induced transparency window.
