A Coherent Kramers-Kronig Receiver for 3-Mode Few-Mode Fiber Transmission

We demonstrate the transmission of 3-mode 24GBaud PDM-16-QAM signals through a 30km 3-mode few-mode fiber using a set of Kramers-Kronig coherent receivers with a novel simplified structure, followed by $6\times 6$ MIMO to undo modal crosstalk.
