“…Therefore, the optical properties of the PCs containing various kinds of materials including dielectrics, metals, metamaterials, semiconductors, plasma, and superconductors (SCs) have been investigated [4][5][6][7][8][9][10][11][12][13][14][15][16][17]. When the constituent materials of PCs are superconductor, or even only a defect layer is a superconductor, superconducting photonic crystals (SC-PCs) are formed [17][18][19][20][21][22][23]. The use of the superconducting photonic crystals has an advantage over conventional metal-dielectric PCs; for example, the loss issue of the PCs can be remedied by the utilization of superconductors, dielectric function of the superconductor depends on the external temperature, etc.…”

Using the transfer matrix method, the present paper attempt to determine the properties of the photonic spectra of the Dodecanacci superconductor-metamaterial one-dimensional quasiperiodic multilayer. The numerical calculation is supported by using the transfer matrix method. At first, we analyze the transmission for Dodecanacci quasicrystal for different generations. After that, we analyze the effect of the thickness of the building blocks and the operating temperature. We observed that a vast number of forbidden bandgaps and transmission pecks are developed in its transmission spectra up to a certain generation number of Dodecanacci quasiperiodic sequence. If the generation number increases further, then the bandgaps become wider. According to the obtained results, depending on its generation, this structure can be used as an optical reflector or narrowband filter.

“…Recently, 1D deterministic multilayered structure including superconducting layers have attracted much attention in developing new kinds of optical filters which make new PQCs devices for optoelectronic system [5,[8][9][10][11]. These quasiperiodic filters have been extended to thermally photonic crystals, including certain cascades superconducting/dielectric layers.…”

In this chapter, we study the properties of specific one dimensional photonic quasicrystal (PQCs), in order to design an output multichannel filter. We calculate the transmittance spectrum which exhibits a photonic band gap (PBG), based on the Transfer Matrix Method (TMM) and the two-fluid model. We show that the generalized Thue-Morse (GTM) and generalized Fibonacci GF(m, n) distributions provide a stacking of similar output multichannel with zero transmission when the input was a sharp resonance of peaks at given n ¼ 2pm where p,isapositive integer. Also, we consider GTM configuration and we apply a deformation y ¼ x hþ1 along the PQC filter, which enhanced the band width of each channel with respect to the number of peaks inside the main transmittance. Here, the coefficient h represents the deformation degree, x and y are thicknesses of the layers before and after the deformation, respectively. This improves the characteristics of PBG.

“…Therefore, they have a great opportunity for application in tunable photonic crystals. Superconducting photonic crystals have illustrated some interesting properties like cutoff frequency [21], narrow transmission resonance [22,23], multichannel transmission [24][25][26], ultrawide band gap [27,28], omnidirectional band gap [29,30], polariton gap [31,32], terahertz radiation [33,34], giant magneto-optical effect [35], negative effective refractive index [36,37], nonlinear response [38], sharp Brewster type transparent window in transmission and reflectance spectra [39], and tunable Fano resonance [40].…”

In this paper, transmission characteristics of onedimensional all superconducting photonic crystals (SPCs) containing high and low temperature superconducting materials have been investigated in visible light region. For superconductor materials, both of the temperature dependence of refractive index and the amount of zero London penetration depth (λ L (0)) are important parameters. According to this, results indicate that by selecting proper superconductors and their thicknesses a wide-band flat-top transmission spectra for SPC structures is acquirable.
