Summary: Optical Backscatter Reflectometry (OBR) is an advanced distributed sensing technique that utilizes optical fibers to detect and localize physical parameters with spatial resolution below the millimeter. By tailoring the Rayleigh scattering properties of optical fibers and enhancing backscattering contents, it is possible to create 2 and 3-dimensional sensing networks, extending OBR to multi-dimensional and even biosensing applications. This work provides a tutorial on distributed optical fiber sensors with enhanced backscattering and discusses the design of sensing networks with these fibers, while also reviewing main applications and emerging topics.

Summary: The temperature sensitivity of ultraviolet written TFBGs in SMF-28 fibers is assessed, and a single gauge factor KT = 6.25×10-6 °C-1 is found to characterize the response to temperature in the 10-50°C range. A simulation model is developed to accurately predict the TFBG spectra in this temperature range. This model enables the complete removal of temperature-induced shifts of all resonances in TFBG sensing applications and accurate measurement of variables of interest using the scaled averages of resonance groups.

Summary: This research analyzes the characteristics of lossy mode resonances (LMRs) in double-clad fibers with a lower refractive index (RI) in the second cladding. Firstly, the LMR spectra are simulated using a 75 nm TiO2 thin film, and it is observed that a thicker second cladding improves the width of the resonances, making them narrower. Then, experimental cases are assessed, showing good agreement with the simulations. Finally, refractometric measurements are carried out in liquids, and the results show that double-clad fibers can improve the performance of LMR-based optical fiber sensors.

Summary: This paper proposes the design of an etched single-mode-multimode-single-mode (E-SMS) fiber-optic-based structure as a multimode interference refractometer for detecting in situ ice formation on different surfaces. The sensor provides higher sensitivity and periodical interferometry bands compared to a basic SMS structure, enabling measurements of surrounding refractive indices with repeatability and robustness. Experimental results demonstrate that the structure can detect the freezing-thawing process of water inside a freezer between -20 degrees C and +20 degrees C. The study also presents a proof of concept for a simple technology applicable in various scenarios such as smart cities, avionics, structural health monitoring (SHM), and cold chain management.

Summary: Double-clad fibers with a lower refractive index second cladding are ideal for enhancing and tuning the sensitivity in LPFGs operating in mode transition. A thin film deposited on the fiber acts as a barrier, preventing the transition of one mode from the first cladding to the thin film. With variation in thin film thickness and refractive index of the surrounding medium, the sensitivity increase and enhancement factors of 4 and 2 have been demonstrated. This concept enhances the performance of LPFGs and offers opportunities for other structures like tilted-fiber gratings or evanescent wave sensors.

Summary: Lossy mode resonance (LMR)-based sensors have been extensively researched in the past decade. These sensors have shown great potential in detecting various physical, chemical, and biological entities. While optical fiber has traditionally been used as the sensing platform for LMR-based sensors, planar waveguide substrates have been introduced in recent years to provide more flexibility in design and better surface immobilization. This study focuses on the impact of substrate thickness on LMR-based optical sensors and demonstrates that a thinner substrate leads to a greater depth in LMR curves, which enhances the sensor's performance in identifying the targeted parameter. This finding expands the applicability of LMR-based sensors in industrial applications.

Summary: Ethylene monitoring is commonly used for controlling fruit ripening, but it is now recognized as an important biomarker in biomedical applications as well. This study presents an optical gas sensor based on lossy mode resonance (LMR) effect for ethylene detection in planar waveguide configuration. Two different approaches, one in the visible (VIS) spectral region and the other in the mid-infrared (MIR) region, were explored. Optical resonances were achieved using sputtered tin oxide thin films. The devices showed different response and recovery times, sensitivities, and limits of detections in the VIS and MIR regions, making them applicable for fruit ripening assessment and hemodialysis control.

Summary: This letter presents the fabrication and characterization of an ammonia gas optical sensor based on lossy mode resonances (LMRs). The sensor utilizes a chromium (III) oxide thin film deposited onto a planar waveguide as the supporting coating for LMRs. The refractive index of the coating changes with the presence and concentration of NH3, leading to a red-shift of the resonance wavelength. The sensor can detect NH3 concentrations as low as 10 ppbv at room temperature and machine learning regression models are used to mitigate the device's cross-sensitivity to temperature and humidity fluctuations.
