In this work, we investigate the sensing performance of Fiber Bragg Gratings (FBGs) engineered to operate near EPs through precise structural tuning. This review provides a comprehensive overview of FBG sensor technology. Abstract—Exceptional points (EPs), intrinsic to non-Hermitian systems, exhibit singular spectral responses with extreme sen-sitivity to external perturbations, offering new opportunities for precision sensing. Researchers have gained enormous attention in the field of fiber Bragg grating (FBG)-based sensing due to its. In the vast realm of optical fiber sensing, where precision and innovation converge, Fiber Bragg Gratings (FBGs) stand as luminaries, casting their influence across myriad applications. Strain sensors based on FBGs are becoming an essential part of smart factory.
