Optical-comb-line selection from a low-power/low-OSNR comb using a low-coherence semiconductor laser for flexible ultra-dense short range transceivers
Optical Fiber Communications Conference and Exhibition, 2015, Pages 1-3.
6.25GHz-spaced optical-comb-line selection either by low-coherence injection-locked laser (LC-ILLD) or with a combination ultra-narrow-filter and low-noise-fiber-amplifier (UNF-FA) is assessed. In a 144Gbps DP-64QAM transmission the LC-ILLD outperforms the UNF-FA approach for comb-OSNR-levels below 30dB.
