Intelligent Fiber Bragg Gratings (FBGs) are advanced optical sensors capable of precise strain, temperature, and deformation monitoring, often enhanced by AI-driven fabrication for high stability and performance.

Overview of Fiber Bragg Gratings

A fiber Bragg grating (FBG) is an optical device created by periodic modulation of the refractive index along the core of an optical fiber. This structure reflects light at a specific wavelength, known as the Bragg wavelength, while transmitting other wavelengths, making it highly suitable for sensing and communication applications.
