title = "Simultaneous Measurement of Axial Strain and Temperature Based on Twin-core Single-hole Fiber with Vernier Effect",
abstract = "An ultrasensitive optical fiber sensor based on the Vernier effect is proposed for simultaneous axial strain and temperature measurement. The sensor structure comprises two cascaded Mach-Zehnder interferometers (MZIs) with different free space ranges. The MZI is built up by fusion splicing a segment of ∼3 mm Twin-core Single-hole fiber (TCSHF) between two pieces of ∼5 mm None core fibers (NCF). The sensor can respond linearly to the axial strain change with a sensitivity of ∼17 pm/μϵ in the range of 0 to 2000 μϵ and high-temperature sensitivity of ∼1.16 nm/ in the range from 30 to 70 . Moreover, the cascaded structure can simultaneously measure the axial strain and temperature change with acceptable error ranges.",
