Summary: Experimental demonstration of liquid refractive index sensing by a fiber optic SPR sensor using copper-zinc oxide bi-layers has shown that the sensitivity of the sensor is affected by the thicknesses of the copper and zinc oxide layers. Sensitivity is found to increase with zinc oxide layer thickness up to 15 nm, but decreases with further augmentation. The optimized thickness of the zinc oxide layer is determined to be 15 nm.

Summary: A photonic crystal (PhC) based 1 x 2 demultiplexer is designed to efficiently operate at 1550 nm, utilizing Y-shaped square-lattice silicon rods and air as the basis. A 15 x 15 rod-based PhC optimized structure with air as its background is proposed through distinct phase studies with different lattice constant and refractive index values. The design achieves enhanced performance with optimal values for refractive index, silicon rod radius, and lattice constant, including higher contrast ratio, high transmission efficiency, fast response time, and low insertion loss, as confirmed by simulation results using the finite-difference-time-domain technique.

Summary: This work discusses the fabrication and sensing performance of fusion structures based on single-mode fiber (SMF) and multimode fiber (MMF) with different cladding diameters, and analyzes the effects of different lengths of MMF and fiber etching on sensing performance. The experimental results show that the SMF-MMF-SMF(SMS)-based structure has better sensing performance. Additionally, the results demonstrate that etched fiber performs better than non-etched fiber, and the etched fiber structure with lower fiber diameters produces more evanescent waves and is better for sensing purposes. Therefore, the proposed structure has certain development potential as an application of future optical fiber sensors.

Summary: This paper proposes a multi-Fano resonances optical refractive sensor with high sensitivity and sharp Fano resonances. The unit cell of the designed structure consists of two asymmetric silicon cylinders on top of a thin dielectric layer. Based on quasi-bound states in the continuum (quasi-BIC), three Fano resonances are excited, which can be applied in multiple object detection. The sensor can achieve three Fano resonances with a narrow linewidth, the maximum Q-factor of 414.93, and the maximum figure of merit (FOM) of 261.67 RIU-1.

Summary: In this study, a titanium dioxide (TiO2) coated etched fiber Bragg grating (eFBG) sensor was used to detect industrial chemicals like glycerin. The FBGs were etched with hydrofluoric acid before applying an optically active thin layer to enhance sensing. Raman spectroscopy and FESEM were used for characterizing the sensor. The sensitivity of the sensor was increased by approximately 24% due to the enhanced interaction between the evanescent field and analyte caused by the metal oxide layer. The TiO2-coated eFBG sensor demonstrated better sensitivity of 13.4 nm/RIU compared to 10.18 nm/RIU achieved by the bare eFBG sensor, surpassing previous works in glycerin sensing.

Summary: In this study, a highly sensitive and selective method for detecting tyramine using localized surface plasmon resonance (LSPR) optical fiber-based sensor is proposed. The sensor is functionalized with MXene and gold nanoparticles to increase the surface area for enzyme immobilization and enhance the sensor performance. The results demonstrate that the developed sensor efficiently detects tyramine with high specificity due to the presence of the tyrosinase enzyme. Further studies reveal the stability, repeatability, and reusability of the proposed biosensor, with a detection limit of 6.96 μM and a sensitivity of 0.0385 nm/μM. Therefore, the optical fiber-based sensor has significant potential for detecting the presence of tyramine in various agricultural and food samples.
