EDFA preamplified recei¨ers can achie¨e sensiti¨ities close to those possible with heterodyne detection while offering a simplified system design. For this sensiti¨ity benefit to be realized, narrow optical bandpass filters are needed to limit the EDFA amplified spontaneous ( ) emission ASE noise. T

Abstract
Reflection performances of sampled Bragg gratings are simulated using the piecewise‐uniform method. The identical characteristics of reflection spectrum are emphasized in terms of the linewidth and reflectivity. A perfect comb filter with identical channel linewidth and uniform reflectivity is demonstrated, employing the sinc‐sampled grating. © 2002 Wiley Periodicals, Inc.

This paper reports the birefringence effects on fiber Bragg grating FBG in sensors, optical communications systems, and devices. We have studied and analyzed the optical and mechanical property changes of FBG when the grating zone is subjected to a static transverse load in the case of plane strain
## 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
## 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
