“…3 and Fig. 7 shows that when incident angle changes from θ0 = 0° to θ0 = 25°, the resonant transmission peak of defect modes for all five samples shift toward lower wavelength side (blue shift) due to change in optical path length of light inside cavity region [26][27][28]. For example, Fig.…”

“…Moreover, FOM of our biosensor is also high and it is of the order of 10 4 . The high value of FOM makes our design suitable for biosensing medical & engineering applications [25][26][27][28][29][30][31].…”

“…Motivated by the aforementioned piece of excellent research work [20][21][22][23][24][25] in this paper we have focused on the fundamental issue, how the change in the refractive index of defect layer dependent on various water borne bacteria samples could be used for photonic biosensing applications, by studying the transmission properties of the proposed structure. This work utilizes the one-dimensional (1D) defective PCs with various water borne bacteria samples due to its simple and low cast fabrication design as compared to two-dimensional (2D) and three dimensional (3D) photonic designs [26,27]. The main idea of our work is to study the localization of photon of specified wavelength of the incident EMWs inside PBG of the proposed structure.…”

The present work deals with photonic sensing technology used for biosensing applications. In this paper we have theoretically examined the transmission properties of one-dimensional (1D) defect photonic crystal (DPC) suitable for biosensing applications. The number of contaminated water samples containing different types of bacteria is poured into the defect layer region and corresponding change in the transmission peaks of defect mode inside photonic bandgap (PBG) has been observed. The proposed structure is composed of two sub-photonic crystals (PCs) containing Si and TiO2 material layers. These two sub-PCs are separated by defect layer of air in which various sensing samples has to be poured one by one. The performance of the proposed biosensor is verified by measuring redshift in the central wavelength of defect mode inside PBG depending upon the change in refractive index of various water borne bacteria samples from 1.333 to 1.43. The sensitivity of the proposed biosensor reaches to high value of 483.6 nm/RIU for Escherichia coli (E. coli) bacteria sample. The proposed biosensor achieves high value of figure of (FOM) of order 104 and low value of limit of detection (LOD) of order 10− 6 which makes our biosensor suitable for biosensing applications.

“…Since the major innovation of this manuscript is to reduce the cost of the proposed sensor, we use the microcavity structure. the 1D-PC is very simple in fabrication than others (2D and 3D) because of its simplest structure and very low cost compared to 2D and 3D structures (Pandey et al 2017 ; Li 2014 ). As cleared in Table 3 , most of the previous works that used the 1D-PC and some of the others that used 2D-PC recorded a very low sensitivity and Q-factor, but in this proposed structure, we recorded a super sensitivity (S = 3300 nm/RIU) at the optimum conditions (Abadla and Elsayed 2020 ; Mohamed et al 2016 ; Banerjee 2009 ).…”

The performance of one-dimensional photonic crystal for plasma cell application is studied theoretically. The geometry of the structure can detect the change in the refractive index of the plasma cells in a sample that infiltrated through the defect layer. We have obtained a variation on the resonant peak positions using the analyte defect layer with different refractive indices. The defect peak of the optimized structure is red-shifted from 2195 to 2322 nm when the refractive index of the defect layer changes from 1.3246 to 1.3634. This indicates a high sensitivity of the device (S = 3300 nm/RIU) as well as a high Q-factor (Q = 10 3 ). The proposed sensor has a great potential for biosensing applications and the detection of convalescent plasma.
