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.

“…As a result, PCLs have been extensively used in a wide range of applications, including filters, [15] mirrors, [16] sensors, [17] absorbers, [18] optical camouflages, [19] and polarization controlling devices. [20,21] The use of defective and cavity-based PCLs such as temperature sensors, [22] chemical sensors, [23] pressure sensors, [24] biosensors, [25,26] and gas sensors [27][28][29][30] has become a hot research topic. For chemical sensing, a D-shaped fiber based on surface plasmon resonance was proposed.…”

The use of plastics can be dangerous due to the numerous industrial chemicals they contain. Di(2‐ethylhexyl) phthalate (DEHP), bisphenol A (BPA), and bisphenol S (BPS) are three detrimental organic chemicals that are used in the plastic industry. In this work, a highly sensitive photonic crystal (PCL) sensor is theoretically proposed and numerically simulated as a detector for DEHP, BPA, and BPS organic chemicals. The proposed PCL is a 1D that has the structure (GaAs/Si3N4/TiN)N/cavity layer/(GaAs/Si3N4/TiN)N, where N is the number of unit cells (UCs). The DEHP, BPA, and BPS analytes are assumed to be separately infiltrated into the cavity layer between two equal numbers of the UCs. The transmission spectra of the PCL are studied using the transfer matrix (TrMx) technique. The most important performance parameter is sensitivity so we have focused on it. A considerable sensitivity enhancement is obtained by raising the defect layer thickness and incidence angle. High sensitivities of 2350.51, 2168.45, and 2042.08 nm RIU−1 are obtained for DEHP, BPA, and BPS, respectively. In the results obtained, the way can be paved for a simple technique to detect chemical compounds.

“…The presence of a photonic band gap (PBG) in the transmittance profile of PCs is a crucial characteristic [4]. Consequently, PCs have been considerably utilized in a variety of applications, including as a narrowband filter [5], an optical absorber [6], and an optical mirror [7], as well as for optical sensing [8], a polarization manipulating device [9], and optical binding [10]. Given that the scaling factor of the PC fabrication process from microto nanoscales was well-matched for both the IR and visible areas [11], photonic crystals (PCs) have been used as a temperature sensor [12], biosensor [13], chemical sensor [14], hydrostatic pressure detector [15], and gas sensor [16].…”

It is very important to design a rapid and sensitive device for the creatinine concentration detection due to it being one of the most considerable benchmarks for efficient kidney working. Here, a novel biophotonic sensor using one-dimensional ternary PC based on Si/TiN/SiO2 layers is proposed for the creatinine concentration detection in a blood serum sample. A central cavity layer is inserted between two equal periodic numbers. The blood sample can be infiltrated in the cavity layer with various creatinine concentrations. Based on the technique of transfer matrix, the transmittance spectra properties are investigated. The influences of variation of the incidence angle for both TE and TM polarizations and the cavity layer thickness are carefully investigated to attain the best sensitivity of the biophotonic detector. A high sensitivity of 938.02 nm/RIU is realized for the suggested detector, which is comparable to most recent works published in this area. Moreover, the proposed sensor has an inexpensive cost, real-time detection, and simple structure, which is helpful to the industrial design using low-cost product nanofabrication techniques. Based on above-mentioned outcomes, our biosensor candidate is a suitable and effective device for the detection of creatinine concentration, and it can use for any biological sample.
