Fiber Bragg Grating
Fiber Bragg Grating (FBG) is a passive filter that is sensitive to environmental changes such as temperature and strain, and is widely used in the fields of optical communication and fiber optic sensors. Its working principle is to form a grating with periodic refractive index modulation in the fiber core, which reflects or transmits light of specific wavelengths. The production process includes standing wave method and fiber surface damage etching method.
