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.
理论与实验相结合的研究表明，光注入会显著改变量子点/量子阱半导体激光器中线宽增强因子（α(H)因子）和调频与调幅指数比（FAIR）的行为。与孤立激光器不同，光注入会降低低频调制下的α(H)因子和FAIR。然而，在高频调制时，光注入对相位-幅度耦合特性影响很小。
