对数据处理和存储的不断增长的需求将需要电子和光子学的无缝单片共集成。相变材料由于其双电光灵敏度、非易失性保持特性和快速开关动态特性而独特地适合于实现这一功能。然而，CMOS电子器件和电介质光子器件之间的极端尺寸差异抑制了高效且紧凑的电驱动光子开关、逻辑和路由元件的实现。在这里，作者通过展示一种光学可访问的电可重构、超紧凑和非易失性存储器，实现了协调这两个领域的重要里程碑。该平台依赖于在等离子体结构内产生的局部热;这独特地允许光学和电读出信号两者与PCM的材料状态互锁，同时仍然确保写入操作是电解耦的。重要的是，通过小型化和有效的热工程，作者实现了前所未有的能源效率，为神经形态和内存计算开辟了一条通往低能耗光电硬件的道路。光是唯一适合传输并行信息和执行高速计算的。在这篇文章中，作者设计了一条由电子驱动的光信号调制、数据存储和计算的路径。通过等离子体结构将光限制在纳米级体积内，并采用活性相变材料，作者展示了具有电学和光学读出的超低能量，非易失性开关。
The ever‐increasing demands for data processing and storage will require seamless monolithic co‐integration of electronics and photonics. Phase‐change materials are uniquely suited to fulfill this function due to their dual electro‐optical sensitivity, nonvolatile retention properties, and fast switching dynamics. The extreme size disparity however between CMOS electronics and dielectric photonics inhibits the realization of efficient and compact electrically driven photonic switches, logic and routing elements. Here, the authors achieve an important milestone in harmonizing the two domains by demonstrating an electrically reconfigurable, ultra‐compact and nonvolatile memory that is optically accessible. The platform relies on localized heat, generated within a plasmonic structure; this uniquely allows for both optical and electrical readout signals to be interlocked with the material state of the PCM while still ensuring that the writing operation is electrically decoupled. Importantly, by miniaturization and effective thermal engineering, the authors achieve unprecedented energy efficiency, opening up a path towards low‐energy optoelectronic hardware for neuromorphic and in‐memory computing. Light is uniquely suited to transport parallelized information and perform high‐speed computations. In this article, the authors have engineered a path for optical signal modulation, data storage and computation driven by electronics. By confining light to a nanoscale volume through plasmonic structures and by employing active phase‐change materials the authors demonstrate ultra‐low energy, non‐volatile switching with electrical and optical readout.
