传感器灵敏度为-0. 074 9 d B/%RH

线性度R2为0. 995。设计的传感器结构紧凑、灵敏度高

可以广泛应用于不同领域的湿度测量。

Abstract

A Mach-Zehnder interferometric relative humidity（ RH） sensor based on optical fiber tapers cascading with core diameter mismatched is proposed. The waist-enlarged fiber tapers are fabricated by two section of the dispersion compensation fiber

and a 6 mm graded-index multimode fiber（ GI MMF） is cascaded by fusion splicing method

which form Mach-Zehnder interferometer. Fiber core diameter mismatched point and graded-index multimode fiber serve as optical couplers. When the external RH changes

the transmission spectrum energy of the sensor will be changed. The experimental results show that the peak power changes with respect to surrounding RH with good linearity. When the RH change in range of 35 %～ 95 % RH

sensitivity of the sensor is-0. 074 9 d B/% RH with linearity R2 of 0. 995. The proposed RH sensor has compact structure

high sensitivity

which makes it possible to be widely applied in RH measurement.
