Paper Abstract

We propose an intra-cavity index sensor based on double cladding ytterbium-doped photonic crystal fiber filled with liquid analyte in the air holes of optical fiber cladding. In such sensor, when pumped by 976 nm light, the output power of the ytterbium-doped photonic crystal fiber laser can be influenced by the refraction index of liquid analyte to achieve the intra-cavity fiber sensing. The numerical analysis shows that the power change is larger in a small range of loss when the end reflectivity is higher, and the sensor’s sensitivity will be higher for the change of refractive index of analyte.
