| Abstract: | In order to overcome the limitation of the existed fabrication techniques of titled fiber Bragg grating (TFBG), a novel method utilizing the asymmetrical holographic interference technique is put forward in this paper. We add a cylindrical lens in the holography light path to focus the circular laser beam into linear shape, and the beam parallel to the material layer, then we can get tilted fiber reflective grating with various angles and flexible fringe spacing. Though controlling the exposure conditions, the reflectivity and bandwidth of the TFBG can be controlled precisely. The simulation and analysis showed that this method has the referential meaning and practical value for fabricating titled fiber Bragg grating. |
