Abstract
We have developed an external cavity self-injection feedback locking (SIFL) system to simultaneously reduce optical linewidth of each individual channel of an InAs/InP qantum dot (QD) 34.46-GHz coherent comb laser (CCL). Optical linewidths are reduced from a few MHz down to less than 300 kHz over 47 filtered individual channels, varying from 5.3% to 9.1% of the original linewidth, between 1531.60 nm to 1544.20 nm. By using this ultra-narrow linewidth QD CCL we have demonstrated 12.032 Tbit/s (16QAM 47x32 GBaud PDM) back to back coherent data bandwidth transmission capacity.
