Fiber Bragg gratings (FBGs) are common components in modern optical communication networks. They are also used in dispersion compensation and wavelength selective devices, fiber lasers, band-rejection filters, and fiber taps, just to name a few [1]. Furthermore, FBGs are extensively employed for sensing strain and temperature changes in industries such as mining, aircraft manufacturing, structural civil engineering and power transmission lines [2]. The wide-spread use of FBGs as sensors stems from their ability to perform read-out tasks in harsh environments. They possess several qualities that make them more attractive than metal strain gauge counterparts. FBGs can measure strains larger than 10,000 µm/m, are immune to electromagnetic interference, are not distance dependent, are intrinsically passive, and are small in size and light-weight allowing for ease of installation with minimal intrusion [3].
