Keywords:Multiplexing and demultiplexing techniques including OTDM, OFDM, OCDM and SDM, Optical transmitter and receiver subsystems

We developed a few-mode receiver potentially independent of the number of modes. The receiver is supported by Kramers-Kronig coherent detection and demonstrated on a 55km few-mode link with 16-WDM spatial-super-channels and total throughput >8 Tbit/s.
