Abstract

We describe three optical comb generation techniques to be used as part of ultra-high bit rate (i.e. above Tb/s) systems: (i) recirculating frequency shifting, (ii) cascade of optical modulators, and (iii) laser gain switching. The comb generators were evaluated in two different scenarios for transmitting a 10-subcarrier superchannel (10 x 112 Gb/s): (i) spectral narrowing due to filter concatenation and (ii) OSNR and signal degradation due to ASE accumulation and standard fiber propagation effects. By using a coherent receiver and offline digital signal processing, the techniques were compared in terms of bit error rate performance.
