“…The three heterostructures are studied in the visible and near infrared (IR) wavelength spectrum. The first heterostructure are designed using the pair of superconductor layers N b (d 1 = 70 nm, T c = 9.25 K, λ 0 = 83.4 nm 28 ), BSCCO as in Figure 1a, (d 2 = 10 nm, T c = 95 K, λ 0 = 150 nm 29 ). Whereas, the second one is made using Rb 3 C 60 (d 1 = 70nm, T c = 30 K, λ 0 = 480 nm 29 ) and in Figure 1b Figure 2 shows the dependence of the reflectance on the normalized frequency of the three proposed heterostructures (a) (Nb /BSCCO), (b) (Rb 3 C 60 /YBa 2 Cu 3 O 7 ) and (c)…”

The Fano resonance and EIR properties in different topological one-dimensional superconductor photonic crystals has been investigated theoretically using the Transfer Matrix Method (TMM). Different types of periodic heterostructures are studied and they are designed by alternating pairs of superconductor materials such (Nb/BSCCO), (Rb 3 C 60 / YBa 2 Cu3O 7 ) and (K 3 C 60 /(BiPb) 2 Sr 2 Ca 2 Cu 3 O y ). All artificial periodic structures are sacked by dielectric cap layer at different induced fields. To exam the efficiency of the reported structures, different parameters are used for analysis such as layers thicknesses, temperature, angle of incidence, the kind of superconductor materials and the dielectric constant of the cap layer. The investigation results exhibit the presence of tunable Fano resonances and EIR resonance peak accompanied by asymmetrical line shape and they are very sensitive to the dielectric cap layer, the superconductor materials and the wave incidence angle.

“…The tunability is induced due the dependency of the refractive indices of the constituent materials of PCs on the external parameters like electric filed, magnetic field, temperature, and pressure etc. [20][21][22][23][24][25].…”

“…Motivated by the aforementioned piece of excellent research work [20][21][22][23][24][25] in this paper we have focused on the fundamental issue, how the change in the refractive index of defect layer dependent on various water borne bacteria samples could be used for photonic biosensing applications, by studying the transmission properties of the proposed structure. This work utilizes the one-dimensional (1D) defective PCs with various water borne bacteria samples due to its simple and low cast fabrication design as compared to two-dimensional (2D) and three dimensional (3D) photonic designs [26,27].…”

The present work deals with photonic sensing technology used for biosensing applications. In this paper we have theoretically examined the transmission properties of one-dimensional (1D) defect photonic crystal (DPC) suitable for biosensing applications. The number of contaminated water samples containing different types of bacteria is poured into the defect layer region and corresponding change in the transmission peaks of defect mode inside photonic bandgap (PBG) has been observed. The proposed structure is composed of two sub-photonic crystals (PCs) containing Si and TiO2 material layers. These two sub-PCs are separated by defect layer of air in which various sensing samples has to be poured one by one. The performance of the proposed biosensor is verified by measuring redshift in the central wavelength of defect mode inside PBG depending upon the change in refractive index of various water borne bacteria samples from 1.333 to 1.43. The sensitivity of the proposed biosensor reaches to high value of 483.6 nm/RIU for Escherichia coli (E. coli) bacteria sample. The proposed biosensor achieves high value of figure of (FOM) of order 104 and low value of limit of detection (LOD) of order 10− 6 which makes our biosensor suitable for biosensing applications.

“…The most considerable property is that there exists a forbidden band in some frequency regions in a typical all-dielectric periodic structure. This forbidden band is also known as a photonic band gap (PBG) [1][2][3][4][5]. In recent years, the other optical properties of a PC containing the so-called doublenegative (DNG) metamaterials have attracted a great deal of attention [6][7][8][9][10].…”

In this work we have obtained the absorption property in one-dimensional (1D) defective lossy photonic crystals (PCs) composed of double-negative (DNG) and double-positive materials by using transfer matrix method. The considered asymmetric geometric structures contain a defect structure at the center of the host crystal as a photonicquantum-well (PQW) with two different types of DNG layers. This study investigates the effect of the stack number of the bilayers PQW defect on the number, position, and the rate of the absorption of anti-resonant modes for both types of the DNG defect. The results show that these factors of the anti-resonant modes depend on the types of the DNG metamaterial corresponding to the defect layers. Accordingly, by changing the types of PQW defect, the anti-resonant modes are red-shifted or blue-shifted as a function of the stack number of PQW. Furthermore, the effect of loss factors on the rate of absorption is examined for the two different types of PQW. The results can present helpful information for designing new types of narrowband and multichannel filters at the microwave.
