摘要： A superstructure fiber Bragg gratings (FBG) by laser-assisted direct writing of on-fiber metallic films. A laser direct write method is used to fabricate periodic films of silver nanoparticles on the non-planar surface of as-fabricated FBGs. Silver films with a thickness of about 9 μm are fabricated around a Bragg grating optical fiber. The performance of the superstructure FBG is studied by applying temperature and tensile stress on the fiber. An opto-mechanical model is also developed to predict the optical response of the synthesized superstructure FBG under thermal and structural loadings. The reflectivity of sidebands in the reflection spectrum can be tuned up to 20% and 37% under thermal and structural loadings, respectively. In addition, the developed superstructure FBG is used for simultaneous measurement of multiple criteria such as force and temperature to eliminate the inherent limitation of regular FBGs in multi-parameter sensing.
