Dispersive bands of bound states in the continuum

Abstract

Bound states in the continuum (BICs), i.e. highly-localized modes with energy embedded in the continuum of radiating waves, have provided in the past decade a new paradigm in optics and photonics, especially at the nanoscale, with a range of applications from nano photonics to optical sensing and laser design. Here we introduce the idea of a crystal made of BICs, in which an array of BICs are indirectly coupled via a common continuum of states resulting in a tight-binding dispersive energy miniband embedded in the spectrum of radiating waves. The results are illustrated for a chain of optical cavities side-coupled to a coupled-resonator optical waveguide (CROW) with non-local contact points.
