Abstract :
An 80 GHz optical clock signal was successfully recovered from a 160 Gbit/s data stream using a regeneratively modelocking scheme of a semiconductor modelocked laser (MLLD). To handle an 80 GHz electrical signal, the MLLD integrated with a high-mesa electroabsorption modulator and a W-band UTC-PD module are used in this scheme.
