Fiber Bragg Grating

FBG (Fiber Brag Grating) is a periodic reflective index modulation in optical fiber core through UV exposure which can achieve the modulation of signal light in optical fiber. It is an indispensable part of a high power fiber laser.

Sets of High Reflectors (HR) and Output Couplers (OC) are available for desired wavelength based on 10/130, 14/250 or 20/400 fibers. We could write FBG on other fiber geometries as per customer demand. High power versions with capability of handling 4000W available.
