Abstract

In this work we demonstrate room temperature lasing from core-shell nanowires consisting of a radial InGaAs quantum well as the active material. The nanowires with the GaAs/InGaAs/InGaP quantum well structures are arranged in a deformed honeycomb lattice, forming a photonic crystal surface emitting laser (PCSEL). We demonstrate lasing from devices with three different nanowire diameters from undeformed, stretched, and compressed honeycomb lattices. Under optical pumping we show that the PCSEL lases at the wavelength of 966 nm (stretched pattern), with the lasing threshold of 103 μJ/cm2. The lasing wavelength increases as the nanowire diameter increases. Combining photoluminescence results and numerical simulations on the field profile and the quality factors of the devices, we establish that the lasing of the device is from the radial quantum well structure.

绝缘体硅衬底上 InGaAs 量子阱纳米线的室温激光

在这项工作中，我们展示了由径向 InGaAs 量子阱作为活性材料的核壳纳米线发出的室温激光。具有 GaAs/InGaAs/InGaP 量子阱结构的纳米线排列在变形蜂巢晶格中，形成了光子晶体表面发射激光器（PCSEL）。我们演示了未变形、拉伸和压缩蜂巢晶格中三种不同纳米线直径的器件发出的激光。在光泵浦条件下，我们发现 PCSEL 的激光波长为 966 nm（拉伸模式），激光阈值为 103 μJ/cm2。随着纳米线直径的增大，激光波长也随之增大。结合光致发光结果以及对器件场廓和品质因数的数值模拟，我们确定器件的激光来自径向量子阱结构。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
