Abstract

The effect of weak optical injection on the threshold gain and resonant frequency of index-coupled DFB semiconductor lasers is theoretically analyzed. The locking bandwidth modification due to injection is discussed for structures having different grating characteristics. Simple formulas are derived which allow comparison of the sensitivity to optical injection for DFB lasers and Fabry-Perot lasers. A symmetrical locking bandwidth is verified and a stability analysis for weak injection is also carried out, imposing a maximum limit of injection rate.
