Latest Patents
Alemohammad holds a patent for an optical fiber sensor and methods of manufacture. This invention involves the creation of superstructure fiber Bragg gratings using a laser-assisted direct writing technique to fabricate periodic films of silver nanoparticles on the non-planar surface of as-fabricated FBGs. The silver films, approximately 9 µm thick, are applied around a Bragg grating optical fiber. The performance of the superstructure FBG is rigorously studied by applying temperature and tensile stress to the fiber. An opto-mechanical model has also been developed to predict the optical response of the synthesized superstructure FBG under various thermal and structural loadings. Notably, the reflectivity of sidebands in the reflection spectrum can be tuned up to 20% and 37% under thermal and structural loadings, respectively. This innovative superstructure FBG is capable of simultaneous measurement of multiple criteria, such as force and temperature, addressing the limitations of traditional FBGs in multi-parameter sensing.
