Abstract
We present a rate equation model for the simulation of quantum dot lasers focusing on modeling the thermal behavior of p-doped devices, which are known to exhibit a reduced temperature sensitivity. The simulation results are compared with experimental data from the literature to demonstrate the model accuracy and underline the impact of npp Auger recombination and intervalence band absorption on the high room-temperature characteristic temperature of p-doped lasers. Applying this model to membrane lasers featuring high optical confinement factors in small active regions due to the use of thin III-V stacks as compared to conventional lasers, we demonstrate the potential of such lasers for short-distance optical interconnects as high temperature (110 °C) operation is predicted for an optimized design, with submilliamp threshold up to 60 °C.
期刊介绍:
The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
