Abstract :
Integrated mode group multiplexer and demultiplexer are proposed for Mode Group Division Multiplexing (MGDM). The architecture with optical MIMO demultiplexing and mode-selective spatial filtering is introduced. Simulations show this architecture can successfully track PDM-DQPSK MGDM signals with mode group crosstalk.
