“…Generally, the photonic crystal has a photonic band gap that can be broken by the creation of a point defect or by a line defect. Several optical devices based on PhCs have been reported by breaking defects such as: demultiplexer [29], switches [30], directional coupler [31], power splitter [32], logic gates [33], triplexer [34], electro-optical modulators [35], add-drop filter [36], filter [37], and sensors [38].…”

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.

“…Several optical detection systems have been used as dual parameter detection platforms such as: dual fiber Bragg gratings [42], cascaded Fabry-Pérot interferometers [43], micro ring resonators for temperature detection [44].These optical detection systems have been used in order to improve the different detection parameters like, the quality factor 'Q', the sensitivity 'S' is the dynamic range. However, due to the reduction in the size of the devices, the optical losses increase and this also limits the growth of miniaturized sensors [45].The use of optical devices based on photonic crystals (Phc) appears for research and the scientific community as the perfect way to reduce the size of the devices to the nanometric scale with ultra-low optical loss which allows a strong confinement of photons [46,47].Several configurations of optical sensors (Phc) have been implemented from which they are based on ring resonators [48], Mach-Zehnder interferometers [49], directional couplers [50], for different applications.…”

The author of this article illustrates a new design and simulation of a twodimensional photonic crystal (PhC) based hydrostatic pressure sensor with a wide dynamic range that ranges from 0 to 4 Gpa and is conducted at a high resolution using the Finite Elements Method (F.E.M) under COMSOL software. In order to analyze the detection principle and its characteristics, the sensor is based on a triangular array PhC-2D of air-immersed silicon rods with a refractive index of 3.6 is used. The sensor consists of a hexagonal shaped ring resonator, which sits between two obtuse angle shaped waveguides. The two waveguides are configured by removing a row of B rods (line faults) and the ring resonator by removing a few rods. This ring resonator reduces the effect of external parameters such as humidity, temperature, etc. The band diagram is presented as well as analyzed using the plane wave expansion (PWE) under the Mat lab software on the one hand and on the other hand, on the other hand, results are obtained and illustrated such as: the distribution of the refractive index 'n' within the structure with the mesh, the distribution of the electric field (TE) at resonance in 2 and 3D, the total energy density (TED), the power flow norm (PFN) and transmission. The sensor is designed for wavelengths between 1520nm and 1640nm.The simulation results show that due to the applied pressure, the refractive index of a sensor is changed and thus the resonant wavelength is shifted linearly to longer wavelengths.The designed sensor behaves linearly between 0GPa and 4GPa of applied pressure and 4.6 nm/GPa of pressure sensitivity.

“…The cost of sample production is extremely high, and preliminary numerical simulation on digital twins allows to reduce the number of test samples and perform a wide range of virtual experiments without any laboratory equipment. Finite-element technologies have proven themselves in modeling various physical processes, including conjugate and multiphysical ones, in domains with contrasting fragments of complex geometry, if thin or curvilinear structures are present in the medium, which are often in nanophotonics [4][5][6] .…”

The paper considers the further development of a nanophotonic supersensitive sensor proposed by the authors earlier.The sensor is oriented for a wide range of engineering applications. The main idea of the device is to estimate the external pressure loading of the sensor by the electromagnetic field measurements. The nanophotonic sensor structure is irradiated by the electromagnetic source operating in the frequency domain. The light beam is passing through the internal cone structure of the sensor, and the output electric field is measured. The proposed mathematical modeling gives the opportunity to connect the radius of the inclusion in the sensor longitudinal section and the output electric field intensity in the reference measurement's point. A 3D simulation of high-frequency electromagnetic wave propagation in a photonic microsensor structure was performed in a formulation close to the real one in the following paper. The mathematical modeling is carried out by the vector finite element method implemented in the author's software. The conducted numerical research allows us to make design decisions about the optimal overall dimensions of the sensor and the operating frequency of the electromagnetic radiation source.
