Paper Abstract

In this paper, we present a novel optical fiber fluorescent temperature sensor based on photonic crystal fiber(PCF) and its theory of forward stimulated fluorescence emission in PCF. It is realized by liquid filling in hollow-core PCF, the liquid is of higher temperature coefficient of refractive index than that of silicon, and is mixed with fluorescent material. Stimulating light and fluorescence propagating in the fiber are in the same direction. Because the band gaps of PCF are modulated by temperature, besides the sensitivity of fluorescence, the stimulating light passing through the photonic crystal fiber is also sensitive to temperature. Experiment results and theory modulation show that when PCF length is shorter than an optimum length, stimulating light in fiber will increase and fluorescence will decline gradually with the increase of temperature.
