Paper Abstract

A system for generating ultra-broadband microwave frequency combs (MFCs) is proposed and investigated. In such a system, a current modulated distributed feedback semiconductor laser (DFB-SL) is utilized to generate a seed resource of MFC, whose comb space can be tuned but bandwidth is relatively narrow. Then, the seed resource of MFC is injected into another DFB-SL for enhancing the bandwidth. The results demonstrate that, after being injected into another DFB-SL, the bandwidth of seed resource of the MFC can be enhanced greatly, and the MFC with bandwidth over 70 GHz can be obtained under suitable injection parameters.
