Abstract

In 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 fibre laser based on a fibre Bragg grating (FBG). In order to achieve this, a new erbium doped fibre 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 variation applied on the FBG and the LPG can be monitored through both the fibre laser wavelength shift and the change of the power level of a unique emission line, both showing a clear linear behaviour.
