“…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 2019, Ramanujam et al have proposed a 1-D photonic crystal with defect nanocomposite layers on either side of the defect layer and a maximum sensitivity of 43 nm/RIU has been achieved for sensing cancer cells 19 .…”

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.

We study the influence of thermal expansion and thermo-optic effect on optical properties of finite one-dimensional three-periodic photonic crystals of structure [(ab) N (cd) М ] K composed of four different nonmagnetic dielectric materials a, b, c, and d. We calculate temperature dependencies and incidence angle dependencies of the transmittivity of TE-and TM-polarized electromagnetic waves, as well as the distribution of energy within these structures. The optimal adjustment of photonic crystal bandgap centers for obtaining the desired transmission characteristics of the temperature-governed photonic bandgap structures is found, and the peculiarities of the energy distributions inside the photonic system are investigated. We propose a sensitive thermal polarization TE|TM switch as well as angular and temperature sensors working at the intraband-mode frequencies exploiting temperature effects.
