摘要

在波分复用系统中，孤子微蜂窝可取代许多独立工作的激光器，在窄栅光通信中发挥重要作用。在这项工作中，我们在一个集成的 4H-SiC 平台上设计并演示了具有 100 GHz 自由光谱范围的高能效孤子微蜂窝。高效光纤耦合（3 dB 插入损耗）、高品质因数微镜（本征品质因数高达 570 万）以及利用拉曼效应对孤子态进行绝热存取等有利技术的结合，使我们能够演示低至 6 mW 的孤子泵浦功率，同时支持泵浦波长附近每条线路超过 -20 dBm 的梳状功率。

Silicon Carbide Soliton Microcomb Generation for Narrow-Grid Optical Communications

A soliton microcomb can play a crucial role in narrow-grid optical communications by replacing many independently operated lasers in wavelength-division multiplexing systems. In this work, we designed and demonstrated power-efficient soliton microcombs with 100-GHz free spectral range in an integrated 4H-SiC platform. The combination of enabling technologies, including efficient fiber coupling (3 dB insertion loss), high-quality-factor microrings (intrinsic quality factors up to 5.7 million), and the employment of the Raman effect for adiabatic accessing of the soliton state, has enabled the demonstration of soliton pump power as low as 6 mW while supporting comb powers above −20 dBm per line near the pump wavelength.

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.
