Paper Abstract

In this letter, a novel optical sensor based on high birefringence fiber loop mirror with a single Fiber Bragg Grating, available for temperature insensitive measurement for strain, was proposed and demonstrated. Considering that the HBFLM (high birefringence fiber loop mirror) and the conditional Fiber Bragg Grating have different response to strain and temperature, respectively, we can detect both the peak wavelength shift of these two devices. So we can build a lineal matrix equation between the perturbation of the surrounding and the shift of the transmission spectrum. Compared with conditional sensors for simultaneous measurement, this kind of sensor has several advantages, including simple configuration, low cost and easy to be fabricated.
