| Abstract: | Presents a mode division multiplexing (MDM) system based on few-mode fiber bragg grating (FBG),the principle of the mode multiplexing/demultiplexing based on few-mode FBG is described.A2 × 2 MDM system is established.The 10 km transmission experiment of the 1.25Gbps and 622Mbps PRBS is achieved successfully,which are carried by LP01 mode and LP11 mode,respectively.The eyediagrams after the 10 km two-mode fiber transmission are given.The BERs for LP01 and LP11mode channel are analyzed when the laser operaes at 1549.228nm.The experimental results prove the feasibility of the mode division multiplexing system based on few-mode FBG,which provides the foundation for the further experiment of mode division multiplexing communication for long distance and high speed rate. |
