TL;DR: Dual Polarization 64 QAM at 100 GBaud performing below the 20% soft FEC threshold of 4×10−2 over 300 km of ultra large effective area fiber at a record line rate of 1.2-Tbit/s is experimentally demonstrated.

TL;DR: It is demonstrated that high-performance low-complexity SSB DD transmissions can be achieved by generating a digital carrier (virtual carrier) together with the complex information-bearing signal at the transmitter using only two digital-to-analog converters.

TL;DR: In this article, a 116 Gb/s on-off keying (OOK), four PAM and 8 PAM optical transmitter using an InP-based integrated and packaged externally modulated laser for high-speed optical interconnects with up to 30dB static extinction ratio and over 100-GHz 3dB bandwidth with 2 dB ripple.

TL;DR: In this article, the authors achieved single-channel 100 Gbit/s transmission using linear unit-ravelling carrier photodiodes and QAM-16 modulation format in the indoor case.

TL;DR: In this paper, the first quadrature phase shift keying (QPSK) data link at 385 GHz, using a photonic-based terahertz (THz) emission and a double heterodyne THz detection, is reported.
