Abstract
A new photonic crystal fiber (PCF) Bragg grating sensor´s scheme is demonstrated for simultaneous measurement of strain and temperature. By writing gratings with similar Bragg wavelengths into two sections of PCF, and filling one of them with alcohol, different temperature sensitivities are obtained while leave the strain sensitivities similar. These gratings are then spliced to form a sensor head, and resolutions are achieved to be 95.26 με and 4.37 °C, respectively.
