Abstract

We propose and demonstrate a novel scheme for discrimination of strain and temperature using a dual polarization distributed Bragg reflector (DBR) fiber laser. By measuring the mean wavelength as well as the polarization beat frequency of the output of the fiber laser, strain and temperature can be determined simultaneously. Experimental results show that the sensor has an accuracy of ±9.5μ and ±0.05.
