“…Figure 3 shows that as the RIX of the analyte increases, the resonant peak position is enhanced. [ 46 ] So, the resonant peak position corresponding to BPS has the highest values. This shift can be explained in light of the Fabry–Perot resonance.…”

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 properties of the defect mode can be tuned using different parameters. In 2022, Alhamss et al have considered the effect of applying magnetic fields, doping rate, and the wide of n-GaAs layer used as a defect layer in a ternary 1-D PC based on Air/(Si/Bi 4 Ge 3 O 12 /SiO 2 ) 4 /defect/(/(Si/Bi 4 Ge 3 O 12 /SiO 2 ) 4 /Air and they demonstrated that the thickness of the defect layer is the most important parameters in control of the defect mode properties 17 . In 2022, Biswal et al have investigated a 1-D semiconductor ternary PC with a complex unit cell and shown that the configuration can be used for designing optical wide−band filters, omnidirectional reflectors at the infrared and terahertz regimes 18 .…”

In the paper, we proposed two new highly sensitive and compact biosensors with ultra-high-quality factors based on the 1-D binary photonic crystal (silicon/air thin layer) with a defect layer. The proposed asymmetric and symmetric biosensors have just a few periods (two to five) on both sides of the defect layer and the normal cell group (INOK) and cancer cells group (YD-10B) are considered for the studies. The effects of different parameters including silicon layer thickness, air layer thickness, defect layer thickness, substrate position, number of periods, and light incident angle are considered in the biosensor operation and the biosensors are optimized based on the sensitivity. The results demonstrate that the sensitivity and defect mode wavelength of the sensors are independent of the substrate position. However, the quality factor and FOM of the sensors significantly depend on the substrate position and they are improved significantly in the symmetric sensor (~ 37% improvement in optimum condition). Also, the high sensitivities of the sensors are maintained over a wide range of silicon and air thicknesses, which is a valuable achievement in the manufacturing process. Furthermore, the sensitivity of the optimized biosensors with a defect layer thickness of 10 microns and only two periods reaches S ~ 2811 nm/RIU which is an excellent sensitivity for an optical biosensor.
