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.
对掺杂量子点激光器热特性的稳态半分析建模以及对薄膜激光器的推断
我们提出了一种用于模拟量子点激光器的速率方程模型,重点是模拟对掺杂器件的热行为,众所周知,对掺杂器件的温度敏感性较低。模拟结果与文献中的实验数据进行了比较,从而证明了模型的准确性,并强调了 npp 奥杰尔重组和间隔带吸收对 p 掺杂激光器高室温特性温度的影响。与传统激光器相比,薄膜激光器由于使用了薄的 III-V 叠层,因此在小有源区内具有高光学约束因子。我们将该模型应用于薄膜激光器,证明了这种激光器在短距离光互连方面的潜力,因为根据优化设计,这种激光器可在高温(110 °C)下工作,亚毫安阈值可高达 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.
