1Results from ref. 4 were based on a non-integrated benchtop laser source and are shown for reference. For this space division multiplexing (SDM) demonstration we quote numbers that are per spatial mode.
*indicates that this figure was not directly provided in the reference, and so is inferred from data provided.
