“…Fiber Bragg grating (FBG) is one of the most popular components, which is widely used in fiber sensing. FBG‐based fiber sensing can be used in several areas such as petroleum mining and vibration sensing , pressure , acceleration and flow, and strain and temperature measurement in composite materials for aircraft, surrounding refractive index (SRI), helicopter structures , and so forth. In the past years, there are many types of fiber sensor, including FBG, tilted fiber Bragg grating (TFBG), and long period fiber grating (LPFG).…”

We proposed and demonstrated a complex sensor, which combined a tilted fiber Bragg grating and a long period fiber grating. We used this sensor to measure the surrounding refractive index and temperature of an unknown liquid. The measured range of the temperature and environmental refractive index were 30–70°CC and 1.33–1.4, respectively. The measured results have linearly trend with high sensitivity. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:1122–1125, 2017

A multiwavelength linear-cavity laser array for long-distance sensing is designed and experimentally demonstrated. It is a semiconductor optical amplifier (SOA) integrating a 1 × N optical switch, formed by a 2 × 2 fiber loop mirror and fiber Bragg grating (FBG) as cavity ends. We investigate the laser system output characteristics and evaluate the sensor performance for different sensing distances incorporating the FBGs. The results show that this SOA-based laser sensor array possesses a dynamic sensing distance of up to 35 km at a 350-mA injection current. Stress/strain detection and reliable linear-cavity fiber laser sensing operation were successfully achieved.

The curing monitoring of the polymeric composite materials has attracted wide interests recently. In order to improve the performance of Gr/Epoxy composites, monitoring the curing process is a demand, especially for the characterization of residual stress after manufacture. The main objective of current research is to explore the application potential of embedded fiber Bragg grating (FBG) to monitor the characterization of the curing process in a Graphite/Epoxy composite. The changes in the shape of the optical spectra, intensity attenuation as well as wavelength shifts in the optical fiber sensors were utilized to assess the curing development and residual stress measurement. The residual stress yielding during curing process was analyzed and presented systematically in this paper.
