“…If we changed the defect layer thickness within the structure from 209 nm to 1000 nm, we will notice that the number of defect peaks increases and shifted to a high wavelength region with the increase of the thickness of the defect layer as shown in Figure 4. This result agrees with previous works [39][40][41] . Therefore, we will use high thicknesses for the defect layer and compare them to get a sensor with high sensitivity.…”

Tuberculosis is one of the most widespread infectious and deadliest diseases in the world. The death percentage is larger than that in the case of the current Coronavirus. Bio-photonic sensors represent a promising option for developing reliable, simple, and affordable tools for the effective detection of tuberculosis. In this paper, a novel design of an optical biosensor will be used as a tuberculosis detector based on a resonance cavity with high sensitivity in one-dimensional photonic crystals demonstrated theoretically. The results show that the increase of the defect layer thickness shifts the defect mode to a longer wavelength region. Besides, it is shifted to a shorter wavelength region via the increase of the incidence angle. The change in thickness of the defect layer and incident angle of light cause an optimization for our suggested structure and the sensitivity reaches 1390 nm/RIU. Our structure is very simple for industrial design.

“…where k is the order of diffraction, λ is the wavelength, D is the interplanar spacing, n eff is the effective refractive index, and ϕ 0 is the angle of incidence. When the angle of incidence of the electromagnetic waves increases, the wave travels a long geometric path through the gas layer 57 . Therefore, the interactions between the electromagnetic waves and gas molecules are improved.…”

Gas sensors are important in many fields such as environmental monitoring, agricultural production, public safety, and medical diagnostics. Herein, tamm plasmon resonance in a photonic bandgap is used to develop an optical gas sensor with high performance. the structure of the proposed sensor comprises a gas cavity sandwiched between a one-dimensional porous silicon photonic crystal and an Ag layer deposited on a prism. the optimised structure of the proposed sensor achieves ultra-high sensitivity (S = 1.9×10 5 nm/RiU) and a low detection limit (DL = 1.4×10 −7 RiU) compared to the existing gas sensor. the brilliant sensing performance and simple design of the proposed structure make our device highly suitable for use as a sensor in a variety of biomedical and industrial applications. Gas sensing has different applications in many fields such as the food industry, medicine, safety, environment, agriculture, and cosmetic 1,2. For example, the detection of volatile organic compounds such as acetone and toluene in exhaled breath is used as a biomarker for many diseases 3,4. In addition, the determination of the concentration of harmful gases such as CO 2 and N 2 O can be applied as an environmental pollution monitor 5. Currently, optical gas sensors are of great interest to researchers because they do not require complicated radioactive/fluorescent labels 6,7. Surface plasmon resonance, Tamm plasmon (TP) resonance, waveguide, and photonic crystal are all examples of platforms for optical sensing 8-12. Photonic crystals (PCs) are useful for a wide range of biomedical and environmental sensing applications. This is due to an impressive set of relevant properties, such as ultrahigh sensitivity, low detection limit, and fast response time 13,14. PC refers to a range of materials characterised by a periodic refractive index along one, two, or three dimensions (1DPC, 2DPC, or 3DPC, respectively). The propagation of electromagnetic waves in PCs can be controlled because of the photonic bandgap (PBG) 15-17. 1DPCs are more appropriate for most applications, given their low cost and ease of fabrication compared to 2DPCs and 3DPCs 18. Recently, PCs have been widely used in various sensor systems. A high-precision gas index sensor, which was proposed by Jágerská et al., reached a sensitivity of 510 nm/RIU based on a PC air-slot cavity 19. Hua-Jun studied a surface plasmon resonance nanocavity antenna array for use as a gas sensor with a high sensitivity of 3200 nm/RIU 20. Wang et al. suggested a guided-mode resonance gas sensor with a sensitivity as high as 748 nm/ RIU 21. Pevec and Donlagic designed a fiber-optic Fabry-Perot gas sensor with a sensitivity of 1550 nm/RIU 22. García-Rupérez et al. presented a highly sensitive device for antibody detection using the slow light regime of a PC waveguide 23. Chen et al. designed a PC/Ag/graphene structure to function as a refractive index sensor based on the Tamm state, with a numerical sensitivity of 1178.6 nm/RIU 24. Auguié et al. studied TP resonance at the interface between a meta...

“…Firstly, the proposed structure is simple and recorded high performance for remote temperature sensing due to the coupling between the porous silicon 1D-PC and Tamm plasmon resonance. Also, for the first time and in contrast to the ordinary [39,40] according to the best of our knowledge, the increase of the incident angle has a negative effect on the sensitivity when the resonant dip approaches the edge of the PBG (Fig. 5).…”

“…For the first time and in contrast to the ordinary according to the best of our knowledge [6,39,40], the increase of the incident angle has a negative effect on the sensitivity of this design. This negative effect of the incident angle on the sensitivity is because the resonant dip has the highest value at the center of the PBG [71], and decreases dramatically with the approach of the resonant dip to the edge of the PBG as clear in Fig.…”

A highly-sensitive remote temperature sensor based on Tamm resonance is proposed using a one-dimensional photonic crystal. The proposed structure is prism/Ag/Toluene/SiO 2 /(PSi 1 /PSi 2) N /Si. The transfer matrix method is used to discuss the interaction between the structure and the S-polarization of the incident radiation waves. We optimized the structure by studying the effect of the incident angle, the thickness of the first and second layers of the photonic crystal unit cell, the porosity of them, and the thickness of the toluene layer. High sensitivity, high signal-to-noise ratio, and very low resolution are achieved due to the coupling between the porous silicon photonic crystal properties and Tamm resonance that makes it very distinguished compared to previous works.
