“…The creation of the photonic band gap is related to the contrast of refractive index n between the constituent materials [22]. In order to locate refractive index [23], high temperature [24], bio-sensing applications [25], pressure [26], force/strain sensor [27], breast cancer [28]. The proposed 2D-PhC structure is simple, small in size with high light confinement, and more convenient compared to one-dimensional and three-dimensional PhC.…”

A biochip is made from a two-dimensional photonic crystal waveguide and a rhombus shape that acts as a resonator. This biochip is a sensor that can detect different concentrations of glucose with amounts of 10, 20 and 60% in water. Here, we studied and simulated the concentrations of glucose, which have a refractive index n of 1.3477, 1.3635 and 1.4394, respectively. To identify these quantities, we have proposed a square lattice structure formed by silicon rods with a n = 3.46. With the help of these dielectric rods immersed in the air, it was possible to analyze the detection characteristics. Our results are examined according to COMSOL software by using the PWE method and the finite element method in order to have the PBG and which helped us to create the structure and extract the propagation at resonance, the field norm, the total energy density (TED), the power flow norm (PFN), the transmission and the sensitivity. The concentrations of glucose in water answered yes to the variations for each of the E-field, the TED, the PFN and the sensitivity. These variations are due to the radius r and refractive index n of each concentration used. This structure can help with diabetes self-monitoring.

“…They found that the appeared states shift to higher energies when we increase the temperature, on the other hand, the increase in pressure causes the state to shift to lower energies [7]. In the other hand, Osswa Soltani et al [8], studied quaternary photonic crystals based on superconductors for higher sensitivity temperature detection, as they found that the temperature causes a noticeable shift to longer wavelengths. We can therefore deduce that for an electronic system, the physical parameter that influences the shift of the electronic states is the effective mass of the materials which depends strongly on the variations of hydrostatic pressure and temperature.…”

This work describes a theoretical and analytical study of a temperature and pressure sensor based on II-VI semiconductors with a simple multi-quantum wells (MQWs) structure. The proposed sensor operates by detecting changes in the intensity (transmission coefficient) and energy of localized electronic states inside gaps under external perturbations of hydrostatic pressure and temperature. Specifically, the proposed MQWs structure is ZnO/Zn1-XMgXO with 10 cells, each containing two materials that form the wells and barriers, respectively. The structure is perturbed by a staircase defect consisting of three defects of the same material or geomaterial. The Green function method is used to study the transmittance of the structure, with cleavage and coupling operators employed. The objective of the work is to explore a new type of defect for use in sensing applications such as multi-quantum well sensors. Key parameters for evaluating the sensor's performance include full width at half maximum (FWHM), sensor sensitivity (S), quality factor (QF), detection limit (DL), signal-to-noise ratio (SNR), dynamic range (DR), detection accuracy (DA), the figure of merit (MF), and standard deviation. These parameters can be optimized by adjusting structural parameters such as the thickness of the staircase or material concentration. The study found that a geomaterial staircase defect provides higher sensitivity to pressure and temperature changes. Additionally, the step (δx) of the staircase defect influences the sensitivity of the localized states: with increasing steps, δx improves sensitivity to temperature and decreases sensitivity to pressure.

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.
