| Title: | Intensity-modulated fiber-optic refractive index and strain sensor based on miniaturized modal interferometer | Authors: | Zhang, N Xu, W Yu, C You, S |
Issue Date: | 2016 | Source: | In Proceedings of 2016 15th International Conference on Optical Communications and Networks (ICOCN), 24-27 September 2016, Hangzhou | Abstract: | A novel intensity-modulated fiber-optic refractive index (RI) and strain sensor based on modal interferometer (MMI) is proposed. The sensing mechanism is mainly based on the Mach-Zehnder interferometer (MZI) constructed by one down taper spliced between dual up tapers on the single mode fiber (SMF). High-order cladding modes are efficiently excited owing to the mismatch of the mode filed diameter (MFD). Experimental investigations achieve a RI sensitivity of-22.437dBm/RIU and a strain sensitivity of 0.0008dBm/μϵ with R2 of 0.9972 and 0.9962 respectively. It has to be noted that this MMI is only made of single SMF and is of low cost and easy fabrication. | Keywords: | Mach-Zehnder interferometer Miniaturized modal interferometer Refractive index Strain |
