High-Temperature sensor based on peanut flat-end reflection structure

Li, Yina; Liang, Zixin; Zhao, Chunliu; Wang, Dongning


A high-temperature sensor based on a peanut flat-end reflection structure is demonstrated. The sensor can be simply fabricated by splicing the spherical end-faces of two segments of single-mode fibers and then cleaving one other end as a flat reflect surface. The proposed structure works as a reflected interferometer. When the ambient temperature changes, the resonant dip wavelength of the interferometer will shift due to the linear expansion or contraction and the thermo-optic effect. As a...[Show more]
