GDS is intuitively easy to use with just two separate Graphical User Interface (GUI) windows and a limited amount of required settings. The aim of GDS is not only to simulate Fiber Bragg Gratings, but also to provide the end-user the parameters to continue fabricating the simulated. Fiber Bragg grating (FBG) sensors have emerged as advanced tools for monitoring a wide range of physical parameters in various fields, including structural health, aerospace, biochemical, and environmental applications. This review provides a comprehensive overview of FBG sensor technology. Sol Photonics has bundled years of experience of Fiber Grating design and manufacturing into an easy to use software package which we named GDS (short for Grating Design Software). Typically, the perturbation is approximately periodic over a certain length of e. a few millimeters or centimeters, and the period is of the order of. Here, we compare two such methods, namely the Hilbert transform (HT) of the device transmission spectrum and standard Fourier spectral interferom-etry. Numerical simulations demonstrate that both methods work not only for ideal, lossless devices but also for ones with realistic absorption.
