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. These microscopic structures within optical fibers have become the bedrock of cutting-edge sensor. Fibre Bragg Grating (FBG) sensors are now a revolutionary technology in the optical sensing area, recognized for their high sensitivity, immunity to electromagnetic interference, and reliability of operation in demanding environments.
Fiber optic pressure sensors use light modulation to measure pressure, offering high sensitivity, EMI immunity, and wide-ranging applications. These sensors are gaining popularity. Fiber-optic sensing (FOS) technology has emerged as a cutting-edge research focus in the sensor field due to its miniaturized structure, high sensitivity, and remarkable electromagnetic interference immunity.
For the past decades, the applicability of distributed optical fibre sensor (DOFS) technology has been widely explored to assess the structural health and integrity. The DOFS has distinctive features compared to t.

Fiber-optic sensors use the physical properties of light when transmitting it via fiber-optic cable with glass or plastic fibers to detect objects. Compared with conventional sensing technologies, FOS demonstrates superior capabilities in. A fiber-optic sensor is a sensor that uses optical fiber either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors"). Fibers have many uses in remote sensing.
Fiber Bragg Gratings or FBGs have achieved significant attention towards sensing and communication applications due to their outstanding advantages. Due to its high sensitivity towards various desig.
Typically the grating period is the same size as the Bragg wavelength, as shown above. Longer periods can be used to achieve much broader responses than are possible with a. A fiber Bragg grating is a periodic or aperiodic perturbation of the effective refractive index in the core of an optical fiber (see Figure 1). a few millimeters or centimeters, and the period is of the order of. When a Bragg grating exists in an optical fiber, it will reflect a specific wavelength dependent on the period of the Bragg grating and the index of refraction of the optical fiber. The underlying. on the core material. The fibre Bragg grating can perform many primary functions, such as reflection and filtering for example, in a highly effi ient, low loss manner. This versatility has stimulated a number of signifi rent back reflection).
