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.A 22 MDM system is established.The 10 km transmission experiment of the 1.25Gbps and 622Mbps PRBS is achieved successfully
which are carried by LP
01
mode and LP
11
mode
respectively.The eyediagrams after the 10 km two-mode fiber transmission are given.The BERs for LP
01
and LP
11
mode 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 mod
e division multiplexing communication for long distance and high speed rate.
