“…As far as we are aware, previous treatments did not proceed to determine the influence of superlattice modes on emitters localized within the structure and in the vicinity of the surface.

Layered structures consisting of finite numbers of charge sheets separating dielectric layers are considered as physically realizable media for the control of dipole deexcitation due to spontaneous emission. The dispersion relation and the corresponding field distributions of a general structure are determined using transfer-matrix techniques. An excited dipole emitter localized in the vicinity of the truncation layer is coupled to the fields supported by such a structure, and its deexcitation rate is evaluated for a number of scenarios in which the structure is characterized by different numbers of charge sheets for varying excitation frequency and varying emitter position. The analysis highlights significant enhancements of the deexcitation rate which can be readily controlled through the adjustable parameters of the structure.

The optical transmission properties in finite periodic superlattice modulated with three-component quasiperiodic defect are presented. The results show that when the multilayered defect is composed of frequency-independent refractive index material, the number of band gaps is increased with the increase of the number of the defect order, and more localized modes emerge. Perfect and wide band gap can be observed when the structural defect is composed of negative refractive index materials. Moreover, the band gap can be adjusted by the incident angle. For a more realistic case where the multilayered defect is composed of frequency-dependent refractive index, the transmission spectra present a rich transmission profile without symmetry.

A three-component quasiperiodic superlattice structures composing of both positive and negative refractive index materials are shown to display resonant transport behavior and optical band gaps. When the structure is composed of nondispersive refractive index material, the number of the resonant transmission peaks increases and the optical band gap becomes broad with the increasing of the medium generation. The band gap covers all the wavelength except for some singular wavelength points when the structure is composed of negative refractive index materials. Moreover, it is found that the spectrum shifts to low frequency for oblique incidence. And with the increasing of the optical thickness, the band gap splits and new perfect transport channels emerge. For a more realistic dispersive negative refractive index material, the transmission coefficients are characterized by a rich transmission profile without symmetry, more wide band gaps and abundance transmissive channels appear.
