The Study on the Fundamental of Fiber Bragg Grating (FBG) Sensing Principle
International Journal for Research in Applied Science and Engineering Technology, 2023 Abstract: A single mode fibre core is laterally exposed to a periodic pattern of powerful UV laser light to create an optical sensor called an FBG. The exposure results in a long-lasting rise in the fiber's core's refractive index (ncore), producing fixed index modulation known as grating (Λ).
