“…For the former, research into slow light is anticipated to be especially useful in the fields of optical telecommunication including all-optical data storage and processing, whereas the latter can dramatically enhance optical absorption, gain, phase shift [80], and nonlinearity [79,16,55,56,9,78], which could improve and miniaturize numerous optical devices such as amplifiers and lasers (see [28,1]). For instance, slow light has been investigated for absorption enhancement for potential applications in increasing solar cell efficiency [19,15,63,14,17], the enhancement of gain or spontaneous emission of lasers [18,61,93,67], the miniaturization of antennas or radio-frequency devices [59,58,94,95,43,87], [36,Chap. 5], and the superamplification in high-power microwave amplifiers [69].…”

Scattering of electromagnetic fields by a defect layer embedded in a slow-light periodically layered ambient medium exhibits phenomena markedly different from typical scattering problems. In a slow-light periodic medium, constructed by Figotin and Vitebskiy, the energy velocity of a propagating mode in one direction slows to zero, creating a "frozen mode" at a single frequency within a pass band, where the dispersion relation possesses a flat inflection point. The slow-light regime is characterized by a 3×3 Jordan block of the log of the 4×4 monodromy matrix for EM fields in a periodic medium at special frequency and parallel wavevector. The scattering problem breaks down as the 2D rightward and leftward mode spaces intersect in the frozen mode and therefore span only a 3D subspaceV of the 4D space of EM fields.Analysis of pathological scattering near the slow-light frequency and wavevector is based on the interaction between the flux-unitary transfer matrix T across the defect layer and the projections to the rightward and leftward spaces, which blow up as Laurent-Puiseux series. Two distinct cases emerge: the generic, non-resonant case when T does not mapV to itself and the quadratically growing mode is excited; and the resonant case, whenV is invariant under T and a guided frozen mode is resonantly excited.
