原始语种摘要: In this paper spectral reflectance and transmission of a low-coherence fiber-optic Fabry-Pérot interferometer with thin ZnO layers is analyzed using a multi-cavity approach. In the investigated setup two standard single-mode optical fibers (SMF-28) with thin ZnO films deposited on their end-faces form an extrinsic Fabry-Pérot interferometer with air cavity. Calculations of the spectral response of the interferometer were performed for different thickness of the layers (50, 100, 150, 200 nm). Based on the obtained results, it can be concluded that the use of ZnO thin films improves the reflectance of the interferometer. Moreover, addition of another cavity can make it possible to perform sensing of two different quantities (e.g. temperature and refractive index). The optimal lengths of the...
