✦ Synopsis

Abstract

A novel temperature‐independent strain sensor based on a fiber Bragg grating is demonstrated. The front section of the fiber Bragg grating is fixed to a crystal plate, and the other section is linearly etched in HF acid. The reflected power of the grating varies linearly with strain and is insensitive to temperature variation. © 2004 Wiley Periodicals, Inc.

## 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 A new scheme is proposed for simultaneous strain and temperature measurement with a single‐fiber Bragg grating. The grating sensor was written on the splice joint between two fibers and has two resonance peaks because of the different refractive index between the two fibers. By bonding
