Long-Haul Coherent Transmission Using a Silicon Nitride Microresonator-Based Frequency Comb as WDM Source

摘要

We demonstrated transmission of polarization-multiplexed quadrature phase-shift keying data over 6000 km using a low-noise silicon nitride microresonator frequency comb as light source. These results show the technology's suitability for long-haul fiber communications.
