Grattan, 'Simultaneous Measurement of Strain and Temperature Using a Single Emission Line,' in Journal of Lightwave Technology, vol. 33, no. 12, pp. 2426-2431, 15 June15, 2015.0733-872410.1109/JLT.2014.2374531https://academica-e.unavarra.es/handle/2454/35957In this work, we present and demonstrate a novel sensor system for simultaneous measurement of strain and temperature through a unique combination of a long period grating (LPG) and a fiber laser based on a fiber Bragg grating (FBG). In order to achieve this, a new erbium doped fiber laser (EDFL) structure is created, showing an optical signal-to-noise ratio (OSNR) of 55 dB and a peak power measured on the OSA between -5 and 0 dBm. The strain and the temperature information can be obtained by using a unique emission line through monitoring both the fiber laser wavelength shift and the change of the power level, both of which showing a clear linear behavior.6 p.application/pdfeng© 2015 IEEE.
