High Temperature Sustainable Tilted Fiber Bragg Gratings Via Femtosecond Laser Plane-By-Plane Writing Technology

In this paper, high-quality tilted fiber Bragg gratings (TFBGs) inscribed by using femtosecond laser and the slit beam shaping technique were reported. By adjusting the included angle between the slit and the fiber, we realized a series of tilted gratings with tilt angles of 0° (FBG), 5°, 10°, 15°,...
