1550nm/1625nm/1650nm
Wide bandwidth
Low insertion loss
The period of chirped fiber grating varies linearly along the grating axially. Chirped fiber grating can be fabricated by a periodic phase mask. This kind of fiber grating has wide spectral bandwidth and special dispersion characteristics. Chirped fiber grating can be used in gain flattening and dispersion compensation communication systems of EDFA and ASE light sources etc.
