Kramers–Kronig Detection with Adaptive Rates for 909.5 Tbit/s Dense SDM and WDM Data Channels

We demonstrate Kramers-Kronig detection of a 909.5-Tbit/s DSDM/WDM signal with adaptive rates through a single-mode 37-core fiber. All 3663 channels (
$37\ SDM\times 99\ WDM$
), derived from one source, exhibit error-free performance, achieving an aggregated spectral efficiency of 184.42 bit/s/Hz.
