Abstract
We theoretically and systematically study the dynamics of carrier density in optically injected VCSELs and correlate it to the observed frequency shift outside the locking region. We also show the dependence of carrier dynamics on all major parameters including frequency detuning, injection level and the linewidth enhancement factor (LEF).
期刊介绍：
Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
