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.

Chirped Fiber Bragg Grating (CFBG) chirped FBG

Chirped fiber grating is a special grating whose grating period changes along the longitudinal direction of the fiber. Xiaoxiao Photon Technology Co., Ltd. uses a phase mask template to write chirped gratings. By adjusting the reflection intensity of the chirped grating, it can be used as a gain flattening filter. Meanwhile, utilizing its ultra wide reflection bandwidth can serve distributed systems.

Standard fiber Bragg grating FBG (uniform/apodized (apodized)/π phase shift/fiber laser matching/tilt/chirp)
