摘要：

In this paper a novel measurement method for temperature has been proposed and investigated based on an ethanol-filled photonic crystal fiber long period grating (PCF-LPG). The ethanol-filled PCF-LPG is sensitive to the refractive index (RI) of internal filled liquid, which will produce a large RI change with surrounding temperature variation and affect the coupling between the core mode and the forward propagating cladding modes. The results indicated that the sensitivity of the proposed temperature sensor can reach 9 nm/degrees C in the range of 20 degrees C to 80 degrees C which is 90 times higher than that of conventional LPG temperature sensors. The simplicity and the excellent performance of our proposed device make it potential for high-precision temperature measurement.
