Experimental study on resonance frequency enhancement of strong optical injection-locked semiconductor lasers

Enhancing resonance frequency of strong optical injection-locked semiconductor lasers is experimentally studied. Resonance frequency is increased from 4.1 to 53.9 GHz by the optical injection locking (OIL) technique. We experimentally demonstrate that resonance frequency is strictly equal to the frequency spacing between the cavity modes of the master and slave lasers under strong OIL condition. This result provides valuable information to improve OIL theory.OpticsSCI(E)EI中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)1ARTICLE12121
