A reflective and high-sensitive refractive index sensor was proposed based on surface plasmon resonance（SPR） with multimode fiber-single mode fiber（MMF-SMF） structure coated with gold film. In order to verify the performance of the reflective sensor, we also made a transmitted SPR sensor based on the multimode fiber-single mode fiber-multimode fiber（MMF-SMF-MMF） structure as comparison. The experiment results showed that the sensitivity of the reflective sensor reached 2029.3 nm/RIU in the refractive index range of 1.3338-1.3804, which was higher than the sensitivity of the transmitted sensor with sensitivity of 1888.8 nm/RIU. Moreover, the reflective probe is robust, easily packaged and suitable for remote measurement.
