摘要

埋藏异质结构(BH)激光器是光纤通信系统和集成光电子学的关键光源。我们已经开始研究这些激光器的低温行为，以期深入了解限制其作为光通信系统直接调制源的性能的机制。特别是，我们关注了量子阱双极性注入过程中量子输运瓶颈的影响，这一机制被广泛认为是限制这些激光器在其最终调制带宽以下工作的原因。

Buried heterostructure lasers for metropolitan area networks: anomalous low temperature behaviour

Buried heterostructure (BH) lasers are key sources for optical fibre communication systems and integrated optoelectronics. We have initiated a study of the low-temperature behaviour of these lasers with a view to gaining insight into the mechanisms which limit their performance as directly modulated sources for optical communications systems. In particular, we have focussed on the effect of quantum transport bottlenecking during ambipolar injection across quantum wells, a mechanism widely viewed as responsible for limiting these lasers to operating below their ultimate modulation bandwidth.
