Plane-by-plane fabrication of fiber Bragg gratings in optical fibers using short-pulse femtosecond IR laser is proposed and demonstrated. By incorporating a cylindrical lens in the fabrication setup, a plane of index modification can be directly insc
By using the plane-by-plane grating inscription method with an fs-IR laser, random fiber gratings with low laser-induced loss were fabricated in SMF-28 fiber for distributed temperature sensing. Compared to conventional random gratings having broadba
