Abstract

Explosive development of artificial intelligence has recently driven strong demand of ultra-large bandwidth interconnects. Optical I/O is considered as a promising approach of implementing ultra-short link data transmission among computing chips. Here, we demonstrated an O-band 8 × 100 Gb/s transmitter based on single quantum dot mode-locked comb laser and arrayed 8-λ microring modulators. The semiconductor laser currently offers the lowest power consumption for multi-wavelength operation and the most compact footprint. All 8 comb channels are modulated at 100 Gbps, with total energy efficiency of the transmitter at 1.66 pJ/bit (laser source included).

用于光互连的基于硅微oring 发射器的高能效、高带宽量子点组合激光器

近来，人工智能的爆炸式发展推动了对超大带宽互连的强烈需求。光 I/O 被认为是在计算芯片间实现超短链路数据传输的一种前景广阔的方法。在这里，我们展示了一种基于单量子点锁模梳状激光器和阵列式 8-λ 微光调制器的 O 波段 8 × 100 Gb/s 发射器。目前，这种半导体激光器在多波长工作时功耗最低，体积最紧凑。所有 8 个梳状通道的调制速率均为 100 Gbps，发射器的总能效为 1.66 pJ/bit（包括激光源）。

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.
