Abstract

In this paper, a novel performance enhancement reservoir computing (RC) system based on the combination of vertical-cavity surface emitting laser (VCSEL) optical feedback and mutual injection (OFAI) structure is proposed and demonstrated numerically. By simultaneously introducing optical feedback and mutual injection structures into the proposed RC system, the nonlinear and high-dimensional mapping capabilities are significantly improved. The proposed system exhibits the best performance in both single task processing mode and parallel processing mode compared to the other 4 RC systems. Specifically, the minimum NMSE of Santa-Fe time series prediction, waveform classification and NARMA-10 task are 0.0011, 1.058 $\times 10^{-8}$ and 0.101 respectively. Furthermore, since two linear polarization modes coexist in VCSELs, the parallel-polarized and orthogonal-polarized configuration is considered. Numerical results show that in all benchmark tasks, the performance of the orthogonal-polarized configuration is generally better than the parallel-polarized configuration in single task processing mode, and the conclusion is opposite in parallel processing mode, which is related to the coupling mechanism between the two polarization modes. Finally, the effect of different parameters on the system performance is explored in detail. In summary, the proposed system is interesting and valuable in the field of high-speed and low-power neuromorphic photonics.

基于 VCESL 光反馈和互注结构组合的性能增强型水库计算系统
本文提出了一种基于垂直腔表面发射激光器(VCSEL)光反馈和相互注入(OFAI)结构组合的新型性能增强型水库计算(RC)系统,并进行了数值演示。通过在拟议的 RC 系统中同时引入光反馈和互注结构,非线性和高维映射能力得到了显著提高。与其他 4 个 RC 系统相比,所提出的系统在单任务处理模式和并行处理模式下均表现出最佳性能。具体来说,Santa-Fe 时间序列预测、波形分类和 NARMA-10 任务的最小 NMSE 分别为 0.0011、1.058/times 10^{-8}$ 和 0.101。此外,由于 VCSEL 中同时存在两种线性极化模式,因此考虑了平行极化和正交极化配置。数值结果表明,在所有基准任务中,在单任务处理模式下,正交偏振配置的性能普遍优于并行偏振配置,而在并行处理模式下,结论恰恰相反,这与两种偏振模式之间的耦合机制有关。最后,详细探讨了不同参数对系统性能的影响。总之,所提出的系统在高速、低功耗神经形态光子学领域具有重要意义和价值。

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.
