✦ Synopsis

The interrogation of fiber Bragg grating sensors with multimode laser diodes is theoretically and experimentally analyzed using two different approaches: serrodyne and dithering techniques. It is also demonstrated that by using several laser modes it is possible to enhance the measurement range without compromising sensitivity.

## 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 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
