TL;DR: An optical fast Fourier transform scheme is demonstrated that provides the necessary computing power to encode lower-bitrate tributaries into 10.8 and 26.0 Tbit s-1 line-rate orthogonal frequency division multiplexing (OFDM) data streams and to decode them from fibre-transmitted OFDM data streams.

TL;DR: Single-laser 32.5 Tbit/s 16QAM Nyquist-WDM transmission with 325 carriers over 227 km at a net spectral efficiency of 6.4 bit/s/Hz is reported.

TL;DR: In this article, a real-time all-optical FFT receiver for OFDM data with line rates of 5.4 Tbit/s or 10.8 T bit/s is presented.

TL;DR: In this paper, the first real-time transmitter with a multicarrier offset-QAM signal at 224 Gb/s after polarization multiplexing was presented and low penalties were achieved in a back-to-back experiment using two high-speed DACs running at 32 GS/s.

TL;DR: A novel 2-channel arbitrary waveform generator (AWG) prototype, generating complex signal constellations with 6-bit digital-to-analog conversion (DAC) of up to 72 GS/s at a 6-dB bandwidth of 23 GHz is presented.
