WebOptical bound states in the continuum (BICs) are special electromagnetic states that remain well localized in photonic structures even though they coexist with outgoing waves that can carry electromagnetic energy away from the photonic structure [ …

WebBound states in the continuum (BICs) are a special kind of spatially localized states with the corresponding frequencies lying in the continuous spectrum. Webversely, a wave state with the frequency inside the continuous spectrum can only be a resonance that leaks and radiates out to inﬁnity. This is the conventional wisdom described in many books. A bound state in the continuum (BIC) is an exception to this conventional wisdom: it lies inside the continuum and coexists with extended waves, but it ...
