摘　　要：对折射率反导引效应对半导体激光器阈值、横模、纵摸、调制等特性的影响作了理论上的分析和总结,并在考虑不同参数的情况下对由此引起的频率啁啾作了数值计算,计算表明,折射率反导引效应对半导体激光器小信号调制频率啁啾的影响程度随器件参数的不同而不同。The influences of the refractive index antiguiding on such performance of the semiconductor lasers as threshold current, transverse mode, longitudinal mode, modulation ans so on are analyzed and summarized theoretically. The frequency chirp arising from this effect is calculated numerically under different parameters. The calculation shows that the extent of the influence on the frequency chirp under small signal modulation varies with the parameters.
