Our experts answer this and other questions. 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 is achieved by creating a periodic variation in the refractive index of the fiber core, which generates a. Fiber Bragg Gratings (FBGs) are periodic variations in the refractive index along the core of an optical fiber, creating a mirror-like effect that reflects specific wavelengths while transmitting others. In this article, we will explore the definition, historical background, and importance of FBGs in modern optics.
