摘要

高灵敏度光纤因其在传感器领域的巨大应用潜力而备受青睐。半导体，如氧化锌，是很好的材料。使用它们作为第二包层为实现下一代多材料光纤提供了机会。利用COMSOL Multiphysics模拟了具有相同曲率半径但不同ZnO薄膜折射率和厚度的异核大弯曲光纤。通过对光纤损耗的测定，确定了ZnO薄膜的最佳厚度。通过模拟和解释在倏逝场中透射率和折射率的关系，建立了加入ZnO薄膜的大弯曲异芯光纤。这些结果将为指导实际操作提供可靠的依据。

Sensitivity Enhancement of Heterocore Macrobend Fiber Optics by Adding a ZnO Film

Optical fibers with high sensitivity are in demand due to their great potential in sensor application. Semiconductors, such as ZnO, are good materials. Using them as a second cladding offers opportunities in realizing next-generation multimaterial fiber optics. COMSOL Multiphysics is used to simulate heterocore macrobend fiber optics with the same curvature radius but different values of refractive index and thickness of ZnO films. The optimum thickness of ZnO films is identified by determining the loss of optical fibers. Macrobend heterocore fiber optics by adding ZnO thin film has been established by simulating and interpreting the relationship in terms of transmission and refractive index in the evanescent field. These results will provide a reliable fundamental to guide the performance in practice.
