## Abstract A novel interrogation of fiber Bragg grating (FBG) in a strain sensor, which is based on Er‐doped fiber laser's transient regime, is reported. The applied strain on FBG changes the laser cavity loss, which in turn modifies the laser's transient regime. The strain value can be obtained b

## Abstract A simple fiber‐Bragg‐grating (FBG) sensor system based on a linear‐cavity fiber laser is proposed and experimentally demonstrated. The lasing wavelength shift resulting from the temperature variation on this sensing element is discriminated by two FBGs. These two FBGs, acting as wavelen
## Abstract This study describes a wavelength‐tunable fiber laser based on a broadband fiber mirror and an etched fiber Bragg grating (FBG) with a tuning range exceeding 15 nm. The experimental results indicate that this configuration provides a simple and economical method of implementing a wavele
## Abstract A semiconductor optical amplifier fiber ring laser (SOAFRL) utilizing a Fiber Bragg Grating (FBG) is demonstrated. The laser operates at a wavelength of 1547.64 nm, equal to the Bragg wavelength. By removing FBG, the SOAFRL shows a multi‐modes output due to the resonant characteristics
## Abstract A fiber Bragg grating strain sensor demodulation system based on the wavelength‐tunable fiber‐ring laser (WTFRL) is developed. The finite impulse response (FIR) digital filter and the centriod detection algorithm (CDA) are implemented to reduce the system noises and to improve the resol
## Abstract A simple refractive‐index fiber sensor based on a tilted Bragg fiber grating (TFBG) interacting with multimode fiber (MMF) is described. The sensor structure is formed by insertion of a small section of MMF between the single‐mode fiber and the TFBG. The average reflective power in the
