title: Frequency-dependent linewidth enhancement factor of optical injection-locked quantum dot/dash lasers.
abstract: Combining theoretical and experimental studies show that optical injection strongly changes the behavior of the linewidth enhancement factor (α(H)-factor) and the FM-to-AM indices ratio (FAIR) in quantum dash/dot semiconductor lasers. In contrast to solitary lasers, both the α(H)-factor and the FAIR at low-frequency modulation are reduced by optical injection. At high modulation frequency, however, the phase-amplitude coupling characteristics are little influenced by optical injection.
