| 摘 要： | 从光场限制因子周期性主烨这一概念出发，指出在纯折射率耦合分布反馈激光器中存在着增益耦合作用，这种作用在阈值附近较小，但在输出功率增加时迅速大，并因此使λ／４相移分布反馈激光器的单模特性主。量子效应对这种增益耦合作用影响不大。在λ／４相移量子阱分布反馈激光器中，量子效应对空间烧孔效应有很强的抑制作用，因此在其高力功率值出特性出中，增益耦合的影响将变得比较明显。

| Abstract: | It is pointed out in this poper that the modulation of optical confinement factorin index coupled DFB lasers can give rise to the gum coupling effect.This effect is smallnear threshold region, but it increases when output POwer increases. The influence of thisgain coupling effect in λ/4 Phase Shifted DFB lasers on threShold gum and frequency shiftis in some way like spatial hole burning.The quantum size effeCt has little influence onthis gain coupling effect. Because the spatial hole burning is much small in MQW lasers, the influence of this gain coupling effect on the threshold gain and frequency shift in MQW lasers will be obliviously. |
