Summary :

The characteristic features of a mutual optical injection-locking system using semiconductor lasers are both analytically and experimentally examined. It is found that in the case of low injection level, locked frequency, locked powers and locking bandwidth of the system are suitably characterized in terms of both a figure of merit specifying unilaterality of optical injection and a modified round-trip phase angle of optical coupling circuit between lasers. The analysis is applicable not only to unilateral optical injection-locking system but also to mutual optical injection-locking system with an arbitrary inverse optical injection. The results of experiment using AlGaAs CSP lasers are found to be in good agreement with the analysis provided that the mutual injection levels are low.
