摘要

我们展示了一种支持动态资源分配的分解式光连接存储器（OCM）架构。我们提出的架构采用了基于硅光子（SiP）微环谐振器（MRR）的无撞击波长选择开关（WSS），内嵌等臂马赫-泽恩德干涉仪，可实现多波长信号的无撞击重路由。利用硅光子交换结构，CPU 节点和两个远程存储器节点之间实现了无差错运行，显示了将光子交换光连接存储器池集成到大规模数据中心和高性能计算（HPC）系统的潜力。

Demonstration of Optically Connected Disaggregated Memory With Hitless Wavelength-Selective Switch

We demonstrate a disaggregated optically-connected memory (OCM) architecture that supports dynamic resource allocation. Our proposed architecture utilizes a hitless wavelength-selective switch (WSS) based on silicon photonic (SiP) micro-ring resonators (MRRs) embedded with an equal-armed Mach-Zehnder interferometer, which permits a hitless rerouting of multi-wavelength signals. Error-free operation is achieved between a CPU node and two remote memory nodes using silicon photonic switch fabrics, showing the potential of integrating the photonic switched optically connected memory pools to the large-scale data centers and high performance computing (HPC) systems.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
