“…The sensitivity of optical devices depends on the properties of the object under investigation; thus, the sensitivity of the same sensor can be different when used for different objects. The influence of such parameters is considered in works [11,13,[24][25][26][27][28][29][30][31][32][33]. Works [16,22,[31][32][33][34][35][36][37] investigate the influence of incidence angle on sensitivity.…”

A new approach to determining the sensitivity of refractive index sensors is proposed. It has been shown that relative and absolute sensitivity show different results, and also, for the first time, it is demonstrated that relative sensitivity has advantages over absolute sensitivity. In addition, the influence of the relative width of the photonic band gap and the difference in the refractive indices of the layers on the sensitivity are examined and the corresponding dependences of these parameters are obtained. We propose these parameters as a convenient tool for optimizing the sensitivity of sensors based on defective photonic crystals. Finally, results are obtained regarding the behavior of the defect mode at the center of the photonic band gap of one-dimensional photonic crystals.

“…Tongyu et al suggested the PC cavity coupled photonic sensor for simultaneously sensing refractive index and temperature by using an electromagnetically induced transparency effect [38]. Recently, Zina et al suggested how 1D PC consisting of cold magnetic plasma and quartz materials according to the Copper mean sequence can be used for the detection of the magnetic field direction by studying the external magnetic field dependent movement of ultra large PBG of the structure [39]. Parandin et al suggested a 2D photonic biosensor made up of circular nano-rings between the waveguides for the detection of various blood components [40,41].…”

In the present research work we have examined the biosensing capabilities of one-dimensional photonic crystals with defects for the detection and sensing of malaria infection in humans by investigating blood samples containing red blood cells. This theoretical scheme utilizes a transfer matrix formulation in addition to MATLAB software under normal incidence conditions. The purpose of considering normal incidence is to rule out the difficulties associated with oblique incidence. We have examined the performance of various structures of cavity layer thicknesses 1000 nm, 2200 nm, 3000 nm and 5000 nm. The comparison between the performances of various structures of different cavity thickness helps us to select the structure of particular cavity thicknesses giving optimum biosensing performance. Thus, the proper selection of cavity thickness is one of the most necessary requirements because it also decides how much volume of the blood sample has to be poured into the cavity to produce results of high accuracy. Moreover, the sensing and detection capabilities of the proposed design have been evaluated by examining the sensitivity, figure of merit and quality factor values of the design, corresponding to optimum cavity thickness.

“…At present, many researchers have proposed one-dimensional (1D) photonic crystal, 7 , 8 photonic crystal slab, 9 , 10 and photonic crystal optical fiber 11 – 13 magnetic sensing structures to improve the sensing characteristics. These structures generally use materials, such as TiO2, SiO2, Si3N4, or nanocomposites, as dielectric layer materials.…”

.A highly sensitive one-dimensional photonic crystal magnetic and thermal sensor with lithium niobite (LiNbO3) used as the defect layer is proposed. The rigorous coupled wave analysis theory and the wavelength interrogation method were performed to further investigate the effects of different defect layers and magnetic fluid film structure parameters on the sensitivity and figure of merit (FOM). The results show that the introduction of LiNbO3 can significantly improve the sensing performance. When LiNbO3 was introduced as the defect layer, the magnetic field detection sensitivity increased from 0.817 to 1.9133 nm / Oe, whereas the temperature detection sensitivity increased from −0.0724 to 0.304 nm / ° C. Meanwhile, it provides a high FOM value of 8.7099 Oe − 1. Our work provides a guideline for the future application of LiNbO3 materials in magnetic and thermal sensors.
