High Power Fiber Bragg Grating (FBG)
Classification:
JUHERE®High Power Fiber Bragg Grating (FBG) is a passive filtering device.lt writes the coherent field pattern of incident light into the core of photosensitive fiber through ultraviolet light exposure, resulting in a periodic change in refractive index along the axial direction of the fiber core. This creates a permanent spatial phase grating, which essentially functions as a narrowband (transmission or reflection) filter or mirror within the fiber core.
