The structure of the FBG can vary via the refractive index, or the grating period. The grating period can be uniform or graded, and either localised or distributed in a superstructure. This innovation tackles old challenges in filtering wide-spectrum optical signals. It promises better performance, more flexibility, and stronger durability. A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. Researchers at Shenzhen University have made a big leap in optical communications.
