基于光的信息处理具有提高电子设备的速度、安全性和可扩展性的潜力，如果可以解决设备复杂性的问题的话。在这里，我们展示了一个集成的纳米电子器件，可以联合收割机，存储和操纵光学和电子信息。采用机械柔性和多层结构，实现了显示忆阻行为的器件。照明显示以几种独特的方式控制设备操作。首先，器件产生光电流，使我们能够以自供电的方式读出器件状态。更重要的是，变化的光强度以成比例的方式调制开关转换，这类似于具有可变可塑性的神经元，并且可以使用光或电输入来教导和查询。这种行为实现了多级光控逻辑和教导方案，其可以应用于基于光的通信设备，并为未来的物联网应用提供了一条通往无处不在和低成本传感器的路线。
Light-based information processing has the potential to increase speed, security, and scalability of electronic devices if issues in the device complexity could be resolved. We here demonstrate an integrated nanoelectronic device that can combine, store, and manipulate optical and electronic information. Employing a mechanically flexible and multilayered structure, a device is realized that shows memristive behavior. Illumination is shown to control the device operation in several unique ways. First, the device produces photocurrent that allows us to read out the device state in a self-powered manner. More importantly, a varying light intensity modulates the switching transition in a proportional manner that is akin to a neuron with variable plasticity and which can be taught and queried using either light or electrical inputs. This behavior enables a multilevel light-controlled logic and teaching schemes that can be applied to light-based communication devices and provides a route toward ubiquitous and low-cost sensors for future intemet of things applications.
