Coherent and incoherent dynamics in quantum dot - semiconductor optical amplifiers (QD-SOA) and novel gain media (A07)

这一提议的目的是为了更深入地了解量子点半导体激光器和新型半导体增益介质在电流注入下的相干和非相干动力学。我们将研究量子点、量子井和层叠的亚单分子膜，以识别和优化束缚态、散射态和载流子路径，并研究结构的维度对载流子动力学的影响。在工作条件下，将通过研究经典和量子区域中的相干光-物质相互作用和噪声来探索器件性能的极限。

The objective of this proposal is a deeper understanding of the coherent and incoherent dynamics in QD-SOAs and novel semiconductor gain media under current injection. Quantum dots, quantum wells and stacks of submonolayers will be studied to identify and optimize bound and scattering states and carrier pathways, and to investigate the influence of the dimensionality of the structures on the carrier dynamics. The limits of device performance will be explored by studying coherent light-matter interaction and noise in the classical and quantum regimes in SOAs under operating conditions.
