The chikungunya virus (CHIKV), transmitted by mosquitos, induces severe symptoms such as joint pain, headaches, and exhaustion, necessitating swift diagnosis and intervention. In this investigation, the transfer matrix method is employed to enhance virus detection using a ternary photonic crystal (PC) biosensor across normal and infected blood constituents-plasma, platelets, red blood cells, and uric acid. These components possess distinctive refractive indices crucial for the biosensor's selective CHIKV detection. A peak sensitivity of 800 nm∕RIU at N ¼ 4 is achieved by analyzing PC transmittance spectrum curves in the presence of diverse blood elements to emulate real-world conditions. Optimal average sensitivity at 1037.5 nm∕RIU is observed at incidence angles of 30 deg, 55 deg, and 80 deg, with 30 deg yielding the highest quality factor of 1015.94. This PC-based biosensor exhibits promise for compact, highly sensitive, and precise virus detection, potentially advancing viral detection biosensor technology and enhancing diagnostic tools for infectious diseases.

One-dimensional photonic crystal-based biosensor for the detection of glucose concentration in human urine

et al. 2023

A biosensor structure based on a ternary photonic crystal (TPC) containing a defect is designed and simulated. This proposed biosensor detects the concentration of glucose in human urine. Based on the transfer matrix method, we theoretically studied the transmission spectra through the TPC presuming blood samples with different refractive indices (RIs) infiltrated into the defect layer of the proposed structures. By varying the concentration of glucose in the urine, the RI of the urine is changed, which in turn changes the sensor's output response; both transmission response and resonance wavelength are affected. We evaluated average sensitivity (S) for the number of periods at different values N for optimization purposes. Our results show that the biosensor has performance parameters for a period value N ¼ 6. Indeed, a value of 1033 nm of full width at half maximum photonic bandgap can be observed with a S of 965 nm∕RIU. The quality factor is 1892.542 and the figure of merit is 756.86 RIU −1 . The proposed biosensor can be a miniaturized structure with extreme sensitivity in the concentration of glucose detection models © 2023 Society of Photo-Optical Instrumentation Engineers (SPIE)

This manuscript focuses on devising a Tellurite-filled circular-timbered PCF that shows considerably highly birefringent and nonlinear characteristics. The impacts of numerous design parameters, such as birefringence (Br), nonlinear coefficients (NLC), confinement loss (CL), effective mode area (EMA), dispersion, numerical aperture (NA), etc. of the fiber are extensively inspected employing the commercially accessible and simulation- friendly COMSOL Software. Besides, the pertinent modal properties of the modeled fiber are rigorously characterized by operating the full-vector finite element method (FEM) with a perfectly matched layer (PML) boundary condition. The simulated findings affirm that the developed fiber exemplifies an ultra-high Br and NLC of 0.0924 and 18900 W-1Km-1 consecutively, at the operational wavelength of 1.55μm. Notably, the offered PCF also reveals a relatively lower CL, a negative-sloping dispersion and a higher EMA at the same wavelength. The pragmatic execution of the modeled fiber is expected to be doable applying the existing fabrication approaches and it can be applied in miscellaneous identical optical domains, namely polarization retention in long-distance communications, optical switching, sensor and laser layout, supercontinuum generation for frequency metrology and so forth.
