Alxenses's FBG offers a series of fiber-optics products based on Fiber Bragg Grating (FBG) technology. FBG is produced in optical silica fibers by creating periodic refractive index variations in the fiber core using UV laser light. FBG is an in-line optical filter and its reflection wavelength and spectral shape depends on the periodicity, length as well as depth of the refractive index changes of the grating structure. FBG exhibits very low loss and is low-cost compared to the bulk-optics counter parts. By altering the grating periodicity and refractive index change, FBGs for various fiber-optics communication and sensing applications can be easily produced.
