Abstract

We presented design, growth and fabrication of the InAs/InP quantum dot (QD) gain materials and the basic performance of the Fabry-Perot QD lasers as compared with the quantum-well (QW) lasers with the same doped materials and structures. By using those QDs we have developed several ultra-low intensity and phase noise coherent comb lasers (CCLs). We have used a 25-GHz QD C-band CCL to successfully demonstrate 10.3 Tbit/s (16QAM 56×23 GBd PDM) back-to-back coherent data transmission for coherent networks and 56×50 Gb/s PAM-4 back-to-back transmission with capacity of 2.8 Tbit/s at a symbol rate of 25 GBaud for data center applications.
