Modeling of long wavelength quantum-dot lasers with dots-in-a-well structure

Summary form only given. The zero-dimensional nature and three-dimensional confinement of QDs give rise to widely-spaced discrete states, resulting in carrier dynamics and lasing characteristics that differ significantly from double heterostructure or quantum well lasers. In this paper, we propose a rate equation model for the dots-in-a-well (DWELL) structure, and analyze the steady-state and transient behavior of the DWELL lasers in detail using the model.
