Abstract

We demonstrate the first experimental investigation on the performance of simplified optoelectronic oscillator (OEO) reservoir computers (RCs) operating on the standard Santa Fe task, comparing our results against numerical simulations. “Simplifying” the OEO by removing the Mach-Zehnder modulator (MZM) and directly modulating the laser diode with the injected signal is an important step towards operationalizing OEO-based reservoir computing (OEO-RC), as this helps pave the way to chip-scale optical reservoir computers where all the components of the reservoir layer can be included in a single fabricated photonic circuit. Our results show that a simplified OEO-RC can meet or exceed the performance of more computationally complex OEO-RC and similar delayed all-photonic RC on benchmark tests, likely indicating suitability for the architecture to process real-world, complex data.

使用直接激光调制光电振荡器的水库计算演示

我们展示了在标准圣达菲任务上运行的简化光电振荡器（OEO）存储计算机（RC）性能的首次实验研究，并将结果与数值模拟进行了比较。通过移除马赫-泽恩德调制器（MZM）并直接用注入信号调制激光二极管来 "简化 "光电振荡器，是实现基于光电振荡器的储能计算（OEO-RC）的重要一步，因为这有助于为芯片级光储能计算机铺平道路，在芯片级光储能计算机中，储能层的所有组件都可以包含在单个制造的光子电路中。我们的研究结果表明，简化的OEO-RC在基准测试中的性能可以达到或超过计算复杂度更高的OEO-RC和类似的延迟全光子RC，这可能表明该架构适合处理现实世界中的复杂数据。

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.
