“…Therefore, sensors based on the phase detection of waves supported by a 1DPhC are feasible [ 22 , 23 , 24 , 25 , 26 , 27 ]. In addition, they represent an alternative to relative humidity sensors based on resonances of surface plasmons [ 16 ], BSWs [ 16 ], whispering gallery modes [ 28 ], guided modes [ 4 , 7 , 29 ], photonic crystal modes [ 30 ], and lossy modes [ 31 , 32 ].…”

Interferometric methods of optical sensing based on the phase shift of the Bloch surface waves (BSWs) and guided waves (GWs) supported by a one-dimensional photonic crystal are presented. The photonic crystal, composed of six SiO2/TiO2 bilayers with a termination layer of TiO2, is employed in the Kretschmann configuration. Under resonance condition, an abrupt phase change is revealed, and the corresponding phase shift is measured by interferometric techniques applied in both the spectral and spatial domains. The spectral interferometric technique employing a birefringent quartz crystal is used to obtain interference of projections of p- and s-polarized light waves reflected from the photonic crystal. The phase shifts are retrieved by processing the spectral interferograms recorded for various values of relative humidity (RH) of air, giving the sensitivity to the RH as high as 0.029 rad/%RH and 0.012 rad/%RH for the BSW and GW, respectively. The spatial interferometric technique employs a Wollaston prism and an analyzer to generate an interference pattern, which is processed to retrieve the phase difference, and results are in good agreement with those obtained by sensing the phase shift in the spectral domain. In addition, from the derivative of the spectral phase shifts, the peak positions are obtained, and their changes with the RH give the sensitivities of 0.094 nm/%RH and 0.061 nm/%RH for the BSW and GW, respectively. These experimental results demonstrate an efficient optical sensing with a lot of applications in various research areas.

“…Therefore, the TMM method is a simple and efficient method to describe the response of the incident waves through periodic structures like 1D PCs (Abadla et al 2021 ; Peng et al 2017 ; Chen et al 2019a ; Razi and Ghasemi 2019 ; Aly and Elsayed 2012 ; Ramanujam et al 2020 ; Born and Wolf 1999 ). Hereinafter, we have considered y as the direction of propagation for the incident EM waves.…”

“…PCs present a new class of periodic structures in which the periodicity of refractive index among one, two, or three dimensions plays the main role in many promising applications (Mehaney et al 2021 ; Abadla et al 2021 , 2020a ; Zhang and Lv 2020 ). Whilst PCs could be designed or fabricated due to the sticking of two materials at least with different optical characteristics (Peng et al 2017 ; Chen et al 2019a ). This hypothesis could be leading in the control of electromagnetic (EM) waves' propagation and photon localization as well.…”

We introduce in this research a simple, accurate, safe, and efficient design for the detection of ethyl butanoate that be present in the dry exhaled breath. In particular, the presence of ethyl butanoate in the dry exhaled breath could be utilized as a platform for the diagnosing of COVID 19. The main idea of this theoretical investigation is based on the inclusion of a cavity layer between a thin layer of Au and the well-known one-dimension photonic crystals. Accordingly, the cavity layer is filled with dry exhaled breath. The numerical results are investigated in the vicinity of the Drude model and transfer matrix method. The investigated results show the appearance of Tamm plasmon resonance in the reflectance spectrum of our design through the IR region. Such resonant mode provides very high sensitivity with the change in the concentration of ethyl butanoate. We have examined the performance of the proposed sensor by calculating its sensitivity, detection limit, detection accuracy, quality factor and figure of merit. The designed sensor could receive sensitivity of 0.3 nm/ppm or 260,486 nm/RIU, resolution of 7 ppm and quality factor of 969.

“…13,14 At present, PCs are one of the hot topics in the research elds of photonics, electromagnetic, biological and biomedical engineering. [15][16][17][18] Breaking the periodicity of photonic structures by introducing a defect within the structure generates a resonant tunneling mode, also called the defect mode, inside the PBG of the structure. [19][20][21] This defect mode allows the incident radiation of the resonant wavelength to pass through the structure, and is very sensitive in sensing any minute changes in the refractive index of the defect layer.…”
