摘      要：A multi-parametric sensor based on multi-mode microfiber(MMF)is proposed,utilizing the modal interference between HE11mode and HE12mode in the elongated multi-mode fiber to achieve the temperature and pressure *** this paper,the simulation model of modal interference based on MMF is established and the mechanism of modal interference is *** the different mechanisms of modal response in the fiber at different wavelengths,the temperature was inverted using the offset of wavelengths in the spectrum,and the pressure was measured using the change of light *** independent measurement of temperature and pressure was *** experimental results show that the sensor has a temperature sensitivity of 1.305 nm/℃.In the case of pressure sensing,the sensor shows a sensitivity of-0.163 d Bm/g.
