## 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

✦ Synopsis
Abstract
An Optical fiber Bragg grating sensor interrogation device based on monolithically integrated echelle diffractive grating and detector arrays on an InP chip is designed and prototyped. The device weighs less than 60 g and measures smaller than 45 mm × 30 mm × 15 mm, and it is specifically designed for potential integration into aerospace applications. This study discusses this device's operation principle and presents some initial experimental results reflecting its performance. © 2007 Wiley Periodicals, Inc.

## Abstract Short‐period fiber Bragg gratings with gratings planes tilted at an angle 8° corresponding to the fiber axis show core mode and a large number of cladding‐mode resonances in transmission. The differences between the cladding‐mode resonance and the core‐mode resonance are used to detect
## Abstract A chemical sensor based on a Bragg grating in the multimode fiber has been demonstrated experimentally. Experimental results indicate that the reflection peak of high‐order mode P2 exhibits a much higher concentration sensitivity of the chemical solution than the reflection peak P1 of t
## 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
## Abstract This article mainly depicts the sensitivity of the pressure sensor based on fiber Bragg grating coated with polymers of different ratio hardener and silicone sealant. The result shows that when the ratio is 1:13, the effect of the sensitivity of 1.94 × 10^−2^/MPa can be obtained. © 2008
