“…However, owing to their bulky and complicated design, which limits their application scenarios, plasmonic optical fibers, such as hollow-core photonic crystal fiber (PCF) sensors, are being increasingly used in SPR sensor development [74]. Hossain et al developed a quasi-D-shaped external Au-coated PCF with significant amplitude sensitivity toward biological samples in the wavelength range of 1080-1560 nm [75]. Label-free PCFs based on Ag/TiN and Ag/ZrN configurations exhibit high sensitivity and linearity for quasitransverse magnetic and electric modes, which can detect unknown analytes as biological sensing devices [76].…”

Issues related to global energy and environment as well as health crisis are currently some of the greatest challenges faced by humanity, which compel us to develop new pollution-free and sustainable energy sources, as well as next-generation biodiagnostic solutions. Optical functional nanostructures that manipulate and confine light on a nanometer scale have recently emerged as leading candidates for a wide range of applications in solar energy conversion and biosensing. In this review, recent research progress in the development of photonic and plasmonic nanostructures for various applications in solar energy conversion, such as photovoltaics, photothermal conversion, and photocatalysis, is highlighted. Furthermore, the combination of photonic and plasmonic nanostructures for developing high-efficiency solar energy conversion systems is explored and discussed. We also discuss recent applications of photonic–plasmonic-based biosensors in the rapid management of infectious diseases at point-of-care as well as terahertz biosensing and imaging for improving global health. Finally, we discuss the current challenges and future prospects associated with the existing solar energy conversion and biosensing systems.

Point-of-care (POC) diagnostic medical devices require simple but sensitive and inclusive detection capabilities. This study develops a unique photonic crystal fiber-based surface plasmon resonance (PCF-SPR) sensor that uses a u-grooved selective coating for extremely sensitive remote and biosensing applications. Scale-down (SCD) air holes control the path that incoming light takes through the sensor in order to activate the free electrons that are present there. To reduce outward radiation, perfectly matched layers (PML) of the absorbing boundary are integrated in addition to optimizing the structural geometry and material thickness. The Finite Element Method (FEM) is employed to quantitatively tune the properties of light directing and sensitivity of the proposed sensor. The proposed sensor has the maximum amplitude sensitivity (AS) of 1189 RIU -1 , the highest wavelength sensitivity (WS) of 12,500 nm/(RIU), and an outstanding resolution of 8.0×10 -6 RIU. The constructed model covers a large refractive index (RI) range of unknown samples, ranging from 1.29 to 1.40. This range allows this sensor to cover the detection of a wide range of bio-analytics, including viruses, cancer cells, carbohydrates, proteins, and DNA/RNA etc. We strongly believe that the suggested sensor will play an extremely useful role in the detection of POC biosample detection.

In order to meet the demand for large-scale magnetic field testing, this paper proposes a D-shaped magneto-refractive photonic crystal fiber (MRPCF) based on surface plasmon resonance (SPR) by using the erbium-doped material. By varying the diameter, location, and number of layers of the air holes, the four different Models A, B, C, and D structures are created, and the corresponding magnetic field sensing properties are analyzed. The simulation findings demonstrate that the magnetic field sensitivities of Models A, B, C, and D are 28 pm/mT, 48 pm/mT, 36 pm/mT, and 21 pm/mT, respectively when the magnetic field strength is 5 - 405 mT. Meanwhile, the figure of merit (FOM) of the four MRPCF-SPR sensors is investigated, which have FOMs of 4.8×10-4 mT-1, 6.4×10-4 mT-1, 1.9×10-4 mT-1, 0.9×10-4 mT-1. Model B has high sensitivity and large FOM. It shows that altering the structural design of the fiber can significantly improve the magneto-refractive effect of MRPCF. The proposed MRPCF has numerous uses in the areas of geological research, earthquake and tsunami monitoring, and military navigation. It can also be expected to enable quasi-distributed magnetic field sensing.
