In this paper, a new type of few-mode fiber, lead sulfide (PbS) doped fewmode fiber is fabricated using modified chemical vapor deposition (MCVD) technique. The fluorescence characteristics of the fiber is characterized. A few-mode fiber amplification system based on the spatial light modulator is built, and the mode gain characteristics of the fiber are measured. The experimental results show that the fiber exhibits ultrawideband near-infrared luminescence when pumped by a 980 nm laser, and the spectral range is from 1 050 nm to 1 650 nm. The LP01 and LP11 mode amplifications are realized with the average modal on-off gain of 4.5 dB and the differential modal gain is less than 0.6 dB within the band from 1 540 to 1 560 nm. The optical fiber provides the feasibility to realize broadband mode amplification in the mode division multiplexing system.
