## Abstract A novel design for simultaneous axial strain and temperature measurement using a PM fiber Bragg grating (PMFBG) concatenated with a Sagnac fiber loop mirror is proposed and demonstrated.The PMFBG acts as a sensor head, and the Sagnac fiber loop mirror serves as a filter to convert wavel

Abstract
We investigate and compare the thermal stability and sensitivity of fiber Bragg gratings (FBGs) obtained from different growth mechanisms, including the well‐known types I, IA, IIA and a new abnormal regime, written in high‐Germanium‐doped optical fiber. The highest stability and sensitivity values are achieved for the type IIA grating. © 2005 Wiley Periodicals, Inc.

A theoretical analysis and experimental study of the strain effect upon a chirped fiber Bragg grating's (CFBG's) wavelength, 3-dB bandwidth, reflectivity, dispersion, time-delay ripple, polarizationmode dispersion (PMD) and so on is presented. The strain effect includes both the exterior stress plac
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 with
