In article number 1900054 by Jesper Mork and co‐workers, the properties of Fano resonances and their use in integrated photonics for realizing optical signal processing are reviewed. The cover image shows a photonic crystal structure, where a Fano resonance is used to realize all‐optical switching. The light beam enters through a line‐defect waveguide and excites a nanocavity, where the light is concentrated and induces nonlinear effects. Interference with the waveguide field leads to switching for ultra‐small light intensity.
