摘要

存储计算（RC）是一种生物启发框架，适用于时间数据处理。在这里，我们提出了一种基于相干检测的全光相干 RC，用于均衡光纤（FO）系统的损伤。我们比较了基于半导体可饱和吸收镜（SESAM）和高非线性波导（HNLW）的 RC 系统的性能。对于非线性惩罚占主导地位的色散管理长距离 FO 系统，我们发现 SESAM 因其较大的非线性存储器而优于 HNLW。相反，对于数据中心网络等短途光导纤维系统中的色散损伤均衡，我们发现 HNLW 因其较大的线性存储器而具有更优越的性能。

Coherent all Optical Reservoir Computing for Equalization of Impairments in Coherent Fiber Optic Communication Systems

Reservoir computing (RC) is a bio-inspired framework suited for temporal data processing. Here we propose an all optical coherent RC for the equalization of the impairments of fiber optic (FO) system based on coherent detection. We compare the performances of the RC systems based on semiconductor saturable absorber mirror (SESAM) and highly nonlinear waveguide (HNLW). For a dispersion managed long haul FO system in which the nonlinear penalty is dominant, we find that the SESAM outperforms the HNLW due to its larger nonlinear memory. In contrast, for the equalization of dispersive impairments in a short haul FO system such as data center networks, we find that the HNLW has a much superior performance due to its larger linear memory.
