First Transmission of a 12D Format Across 3 Coupled Spatial Modes of a 3-Core Coupled-Core Fiber at a Spectral Efficiency of 4 bits/s/Hz
We demonstrate the first transmission of a new twelve-dimensional modulation format over a three-core coupled-core multicore fiber. The format occupies a single time slot spread across all three linearly-coupled spatial modes and shows improved MI and GMI after transmission compared to PDM-QPSK.
