In contrast to a conventional symmetric Lorentzian resonance, Fano resonance is
predominantly used to describe asymmetric-shaped resonances, which arise from the
constructive and destructive interference of discrete resonance states with broadband
continuum states. This phenomenon and the underlying mechanisms, being common and
ubiquitous in many realms of physical sciences, can be found in a wide variety of
nanophotonic structures and quantum systems, such as quantum dots, photonic crystals …
