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.
