140-Gbaud QPSK Transmitter Using Ultra-High-Speed Driver and I/Q Plasmonic Modulator on Silicon Photonics

We report on coherent transmission of beyond 100 GBd signaling based on plasmonic technology. Using dual-drive plasmonic-organic-hybrid I/Q modulator on silicon photonics platform, we demonstrate the successful transmission of 160-GBaud QPSK and 140-GBaud 16QAM modulations.
