Title
An Optical Fiber Sensor for Axial Strain, Curvature, and Temperature Measurement Based on Single-Core Six-Hole Optical Fiber
Abstract
In this paper, the field distribution and effective refractive index of transmission modes in single-core six-hole optical fiber were researched by modeling and simulation experiments. Based on the simulation results, a new type of sensor for axial strain, curvature, and temperature applications measurement was designed and fabricated. The experimental results showed that the axial strain sensitivities at different dips were -0.97 pm/mu epsilon and -1.05 pm/mu epsilon in the range from 0 to 2000 mu epsilon, and the temperature sensitivities were 35.17 pm/degrees C and 47.27 pm/degrees C in the range from 25 to 75 degrees C. In addition, the proposed sensor also detected the curvature change with sensitivities of 7.36 dB/m(-)(1) and 20.08 dB/m(-1) from -2.582 m(-1) to -1.826 m(-1), respectively. Finally, through theoretical analysis, it can be deduced that this has potential application in the field of simultaneous measurement of strain and temperature.
