英文摘要： Microstructure optical fibers possess many distinguished characteristics compared with conventional optical fibers. The micro/nano-scale air holes in Microstructure optical fiber make it possible for the combination of optical fibers with functional materials. Filling material into the air holes of Microstructure optical fiber is an effective way to achieve a variety of sensors and resolve cross sensitivity. In this project, the mechanism and applications of multi-dimensional and multi-parameters sensor based on composite microstructured fiber gratings will be studied. Combined with the excellent characteristics of fiber gratings, the outstanding guiding properties of Microstructure optical fibers could be well synthesized with the unique physical characteristics of the optical, electrical, magnetic, and thermal materials infiltrated into Microstructure optical fibers. And thus several optical properties, including guiding mechanism, mode coupling, birefringence, and dispersion, could be controlled, which would be of great significance for the research on the light-matter interaction and development of fiber-based opto-electronic devices as well as sensing components. Composite microstructured fiber gratings, as the research object, its response characteristics at various external physical field effects would be studied. The applications of multi-dimensional and multi-parameters sensor based on composite microstructured fiber gratings would also be studied according to actual environment (with Temperature, Stress, Relative humidity, Magnetic field intensity, and electric field intensity). This research project has important scientific significance and practical value. And moreover, we hope to further promote the development of fiber optic sensing areas.
