We derive tight upper and lower bounds of the ratio between decay rates to two ports from a single resonance exhibiting Fano interference, based on a general temporal coupled-mode theory formalism. The photon transport between these two ports involves both direct and resonance-assisted contributions, and the bounds depend only on the direct process. The bounds imply that, in a lossless system, full reflection is always achievable at Fano resonance, even for structures lacking mirror symmetries, while full transmission can only be seen in a symmetric configuration where the two decay rates are equal. The analytic predictions are verified against full-field electromagnetic simulations.

Induced transparency, an interference effect due to mode coupling, has attracted significant research interest. The first discovered and most striking type of induced transparency plays electromagnetically induced transparency (EIT) in atomic systems. Optical cavities serve as a more ideal and feasible platform for realizing the effects of induced transparency, which leads to considerable demonstrations in theory and experiments. This review provides a run‐through of research findings on different types of induced transparency phenomenon, including, inter alia, EIT, optomechanically induced transparency, plasmon‐induced transparency, Brillouin scattering induced transparency, optically induced transparency, photothermally induced transparency, and dipole‐induced transparency. Their mechanisms, developments, techniques, and applications are discussed in detail. Most importantly, the emerging area of induced transparency at exceptional points is analyzed for its great promise. The last section presents a brief summary and perspective of induced transparency with optical cavities.
