摘要

本文提出了一种基于少模光纤布拉格光栅（Few-mode FBG）的模分复用通信系统，阐述了基于少模光纤布拉格光栅的模分复用/解复用原理，建立了22的模分复用实验系统，分别利用LP

和LP

模作为独立信道，实现了1.25Gbps和622Mbps两路伪随机序列（PRBS）的10km传输实验，给出了传输后的眼图，分析了当激光器波长为1549.228nm时，实验系统的误码特性.实验验证了基于少模光纤布拉格光栅的模分复用通信系统的可行性，为进一步实现长距离高速率的模分复用通信奠定了实验基础.

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.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

mode and LP

mode

respectively.The eyediagrams after the 10 km two-mode fiber transmission are given.The BERs for LP

and LP

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.
