英文摘要：

We generate multiple optical carriers with ultra-low phase noise, over a useable bandwidth of 160 GHz, from an externally injected gain-switched comb source with exceptional low linewidth below 10 Hz. We show successful transmission of 17 demultiplexed channels using 64-quadrature amplitude modulation signals at 5 GBaud.
