摘要	In this paper, an ultra-long period fiber grating (ULPFG) based on periodically embedding multimode fiber into single mode fiber (PEM-ULPFG) is proposed to simultaneously measure liquid refractive index (RI) and temperature with high sensitivity. Five resonant dips belong to different cladding mode and diffraction mode orders appear in the transmission spectrum. The responses of the dips to refractive index and temperature are different. Therefore, high sensitivity and dual-parameters measurement are realized. Numerical simulation based on beam propagation method (BPM) is also carried out to design and optimize the parameters of the device. Experimental results show that the maximum RI sensitivity of -1230 nm/RIU in the range of 1.4021-1.4383 RIU is achieved by tracing the target dip (dip 4). The temperature response of the dip 4 is also characterized to be as low as 52.6 pm/C. Another dip (dip 5) is used for measuring temperature with the temperature sensitivity of 92.3 pm/C. Different responses to the external changes of the dips obtained by the PEM-ULPFG makes the proposed sensor competitive in the field of high sensitivity and dual-parameter sensing. IEEE
