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 wavelength discriminators, are used to increase the real‐time measurement range for monitoring the temperature variation. © 2003 Wiley Periodicals, Inc.

## Abstract An efficient linear cavity Brillouin fiber laser (BFL) is demonstrated using a standard single mode fibre (SMF), an optical coupler and a fiber Bragg grating (FBG). The laser peak is obtained at −4.5 dBm with a Brillouin pump of 14 dBm. The use of a 99/1 optical coupler shows the highes

## 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
