Chirped FBG
Chirped gratings are structures where the optical period of the index modulation varies along the grating length. AtGrating manufactures the chirped grating by using chirped phase mask. By modifying the intensity of grating depth for reaching any predefined gain compensation profile that creates the gain flat filter. With ultra wide bandwidth that also create wide band filter as well as serving the distributed sensing.

Applications:
Gain Flattening Filter
Dispersion compensation
FTTH
CWDM system

Features:
Wide Bandwidth
Low Insertion Loss
High Reflectivity
