摘要

在探索可集成 CMOS 的 GeSn 光源方面取得的最新进展包括在室温下工作的光泵浦激光器和首次展示的电泵浦激光器。在这项研究中，我们评估了电泵浦双异质结构 GeSn 环形激光二极管的性能与几何形状和泵浦脉冲时间的关系。特别是讨论了带状结构（即 GeSn 带隙的直接性）与器件散热之间的权衡，以及它们对发射强度和阈值电流密度的影响。

Electrically Pumped GeSn Micro-Ring Lasers

Recent progress in the quest for CMOS-integrable GeSn light sources comprises the optically-pumped laser operating at room temperature and the first demonstrations of electrically pumped lasers. In this work, the performance of electrically-pumped double heterostructure GeSn ring laser diodes are evaluated as a function of their geometry and pumping pulse time. In particular, the trade-off between the band structure, i.e., the directness of the GeSn band gap, and the device heat dissipation is discussed in terms of their impact on the emission intensity and threshold current density.

期刊介绍： Papers published in the IEEE Journal of Selected Topics in Quantum Electronics fall within the broad field of science and technology of quantum electronics of a device, subsystem, or system-oriented nature. Each issue is devoted to a specific topic within this broad spectrum. Announcements of the topical areas planned for future issues, along with deadlines for receipt of manuscripts, are published in this Journal and in the IEEE Journal of Quantum Electronics. Generally, the scope of manuscripts appropriate to this Journal is the same as that for the IEEE Journal of Quantum Electronics. Manuscripts are published that report original theoretical and/or experimental research results that advance the scientific and technological base of quantum electronics devices, systems, or applications. The Journal is dedicated toward publishing research results that advance the state of the art or add to the understanding of the generation, amplification, modulation, detection, waveguiding, or propagation characteristics of coherent electromagnetic radiation having sub-millimeter and shorter wavelengths. In order to be suitable for publication in this Journal, the content of manuscripts concerned with subject-related research must have a potential impact on advancing the technological base of quantum electronic devices, systems, and/or applications. Potential authors of subject-related research have the responsibility of pointing out this potential impact. System-oriented manuscripts must be concerned with systems that perform a function previously unavailable or that outperform previously established systems that did not use quantum electronic components or concepts. Tutorial and review papers are by invitation only.
