A novel MUX/DEMUX based on few-mode FBG for mode division multiplexing system

摘要

In this paper, a novel mode multiplexer/demultiplexer (MUX/DEMUX) based on few-mode fiber Bragg gratings (FBG) has been proposed. The principle of the MUX/DEMUX based on few-mode FBG has been described in detail, and crosstalk of better than 20 dB is obtained experimentally. Then a 2 x 2 division multiplexing (MDM) system has been established with the MUX/DEMUX we proposed. The transmission experiment of 2 x 10 Gbps PRBS has been achieved successfully, which are carried by LP01 mode and LP11 mode, respectively. When the receiver sensitivity is greater than - 14 dB m and - 10 dB m, the BER can both reach 10(-3) for B2B and 10 km transmission, respectively. (C) 2016 Elsevier B.V. All rights reserved.
