Efficient Digital Coherent Detection of A 1.2-Tb/s 24- Carrier No-Guard-Interval CO-OFDM Signal by Simultaneously Detecting Multiple Carriers Per Sampling
Coherent communications Phase modulation
2015/6/10
We experimentally demonstrate efficient detection of a 1.2-Tb/s 24-carrier NGI-CO-OFDM signal with 12.5-Gbaud PDM-QPSK carrier-modulation by simultaneously recovering 2 or 3 carriers per 50-GSamples/s...
240-Gb/s Polarization-Multiplexed 64-QAM Modulation and Blind Detection Using PLC-LN Hybrid Integrated Modulator and Digital Coherent Receiver
Polarization-Multiplexed 64-QAM Modulation Blind Detection PLC-LN Hybrid Integrated Modulator Digital Coherent Receiver
2015/7/20
We demonstrate 240-Gb/s 64-QAM signal modulation and detection. 20-Gbaud 64-QAM signals are generated employing hybrid integration of silica PLCs and LiNbO 3 phase modulators, and demodulated with a d...
