Abstract

As novel passive optical components, fiber gratings have a comprehensive prospect in optical communication and sensing systems, due to their excellent optical properties. Blazed fiber Bragg grating, an important member of fiber gratings, because of its special structure, not only has all properties of fiber Bragg grating, but also has its own unique properties. With the fiber sensitivity enhanced and the technology of fabrication fiber grating improved, blazed fiber Bragg grating with an excellent character comes true, which have been used in the area of gain flatten, sensing system and wavelength demodulation. The sensing theory of blazed fiber Bragg grating is presented in the paper. Theoretical and Experimental research on its temperature sensing characteristic, strain sensing characteristic have been taken. The blazed fiber Bragg grating has the same temperature sensing and strain sensing characteristic as fiber Bragg grating. The temperature sensitivity experiments of the grating have been studied. By packaging fiber gratings with a special type of polymer, the experiments indicate that the temperature sensitivity to seven times.
