218-Gb/s single-wavelength, single-polarization, single-photodiode transmission over 125-km of standard singlemode fiber using Kramers-Kronig detection

We demonstrate a 218-Gb/s direct detection receiver using Kramers-Kronig optical phase reconstruction and chromatic dispersion compensation based on a single photodiode and achieve single-span transmission over 125 km of standard singlemode fiber at 1550 nm.
