If you have a question about this talk, please contact Dr Miguel Navarro-Cia. Recently, a novel way of light confinement in unbounded photonic structures was demonstrated by means of so called bound states in the continuum (BIC) [1]. In these states, which are mathematically characterized by infinite quality factor, light is localized within the structure supporting the BIC mode, despite the mode frequency lies in the continuum part of the spectrum, therefore coexisting with the radiative leaky modes. We discuss optical and topological properties of BICs and overview recent advances in realization of devices for active, nonlinear and topological photonics, which are based on the BIC concept. We discuss how BIC localization mechanism can be used to achieve strong mode coupling and high-Q states in isolated subwavelength nanoscale resonators [2]. [1] Bound states in the continuum, C. W.
