Quantum dot waveguides: Ultrafast dynamics and applications
DTU Fotonik, Department of Photonics Engineering, Technical University of Denmark, Lyngby, Denmark1
In this paper we analyze, based on numerical simulations, the dynamics of semiconductor devices incorporating quantum dots (QDs). In particular we emphasize the unique ultrafast carrier dynamics occurring between discrete QD bound states, and its influence on QD semiconductor optical amplifiers (SOAs).
Also the possibility of realizing an all-optical regenerator by incorporating a QD absorber section in an amplifier structure is discussed.
