摘要

InAs/GaAs量子点（QD）分布反馈（DFB）激光器是下一代光子集成电路的理想选择。我们提出了一种包含氧化孔径限制表面光栅（OASG）结构的设计，该结构减少了传统制造方法（包括蚀刻和再生）制造的器件中的非辐射复合损耗和表面光学损耗。OASG-DFB激光器消除了脊波导刻蚀的需要，避免了侧壁光栅耦合的不稳定性。实验结果表明，单模工作稳定，最大输出功率为15.1 mW，侧模抑制比为44 dB，线宽为1.79 MHz。这种方法简化了制造，降低了成本，并增强了基于gaas的QD DFB激光器在光通信和光子集成中的应用的可扩展性。

Single-mode InAs/GaAs quantum-dot DFB laser with oxidized aperture confined surface grating

InAs/GaAs quantum dot (QD) distributed feedback (DFB) lasers are promising candidates for the next-generation photonic integrated circuits. We present a design that incorporates an oxidized aperture confined surface grating (OASG) structure, which reduces non-radiative recombination losses and surface optical losses sustained in a device fabricated by conventionally fabrication methods including etching and regrowth. The OASG-DFB laser eliminates the need for ridge waveguide etching and avoids instability in sidewall grating coupling. Experimental results show stable single-mode operation, a maximum output power of 15.1 mW, a side-mode suppression ratio of 44 dB, and a narrow linewidth of 1.79 MHz. This approach simplifies fabrication, reduces costs, and enhances the scalability of GaAs-based QD DFB lasers for applications in optical communication and photonic integration.

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.
