首次测量了垂直腔面发射激光器（VCSEL）的动态波长漂移或直接调制。在0.98 μ mInGaAs-GaAs VCSEL的谐振频率处的最大波长偏移约为0.7AA。作者通过速率方程的大信号分析计算了波长漂移。通过对实验数据的理论拟合，估算出线宽增强因子α为4。>
The dynamic wavelength shift or directly modulated vertical-cavity surface-emitting lasers (VCSELs) has been measured for the first time. The maximum wavelength shift at the resonance frequency of a 0.98 mu m InGaAs-GaAs VCSEL is approximately 0.7 AA. The authors calculated the wavelength shift by a large signal analysis using rate equations. The linewidth enhancement factor alpha is estimated to be 4 by fitting the measured data with the theory. >
