“…Refractive indices of pure water, vibrio cholera, Escherichia coli (E. Coli) and shigella flexneri are 1.333, 1.365, 1.388 and 1.422, respectively [4]. Photonic crystals (PCs) and electromagnetic wave propagation have been widely discussed during the last three decades at both the design and manufacturing stages [5,6]. In a PC, light propagation is controlled by several layers of dielectric materials with low and high refractive indices [7].…”

Today, detecting processes of waterborne bacteria in drinking water is a global challenge because these bacteria can lead to dangerous diseases to the human body. In this paper, we have developed a new sensor for the detection of waterborne bacteria based on a one-dimensional (1D) defective binary photonic crystal. The defect layer is taken as a water sample located in the middle of the photonic crystal structure. A resonant peak is then created within the photonic bandgap. The sensing mechanism of the proposed detector is based on the refractive index difference between pure water and waterborne bacteria samples. This index change leads to a shift in the resonant peak position in the transmission spectrum. The effects of many parameters, such as incident angle, defect layer thickness, thicknesses of periodic layers and the number of periods on the sensitivity are investigated. At the optimum conditions, the proposed sensor exhibits a sensitivity of 3639.53 nm/RIU which is ultra-high compared with recently published biosensor papers. The proposed design could distinguish between the different types of waterborne bacteria although the minute difference between their refractive indices. In addition to that, it has a simple design so that it can be easily fabricated.

One-dimensional photonic crystal-based biosensor for the detection of glucose concentration in human urine

A biosensor structure based on a ternary photonic crystal (TPC) containing a defect is designed and simulated. This proposed biosensor detects the concentration of glucose in human urine. Based on the transfer matrix method, we theoretically studied the transmission spectra through the TPC presuming blood samples with different refractive indices (RIs) infiltrated into the defect layer of the proposed structures. By varying the concentration of glucose in the urine, the RI of the urine is changed, which in turn changes the sensor's output response; both transmission response and resonance wavelength are affected. We evaluated average sensitivity (S) for the number of periods at different values N for optimization purposes. Our results show that the biosensor has performance parameters for a period value N ¼ 6. Indeed, a value of 1033 nm of full width at half maximum photonic bandgap can be observed with a S of 965 nm∕RIU. The quality factor is 1892.542 and the figure of merit is 756.86 RIU −1 . The proposed biosensor can be a miniaturized structure with extreme sensitivity in the concentration of glucose detection models © 2023 Society of Photo-Optical Instrumentation Engineers (SPIE)

For the improvement of daily needs, the use of many chemicals is growing rapidly. Some of these compounds are harmful to human health. Moreover, due to the wide range of applications in industry, it has become necessary to develop rapid and accurate detectors for chemical compounds. Herein, a new chemical photonic structure is theoretically investigated as a detector for isopropanol, ethanol, and acetone. The proposed sensor is based on a 1D ternary photonic crystal and has the structure (Si/Si3N4/SiO2)N/cavity layer/(Si/Si3N4/SiO2)N. The organic chemical compounds are assumed to be separately infiltrated into the cavity layer. The defect layer (DLR) thickness, incident angle, number of unit cells, and the contrast between the high‐ and low‐index layers are varied and the sensitivity and quality factor are found for each case. The sensitivity can be considerably improved by increasing the DLR thickness, angle of incidence, and the contrast between the high‐ and low‐index materials. An extremely high sensitivity (2270.48, 2283.0555, and 2283.75) and quality factor (21.82 × 105, 21.48 × 105 and 21.46 × 105) are obtained for isopropanol, ethanol, and acetone. The results described earlier may pave the way for a practical and useful method of diagnosing chemical compounds.
