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.
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.
