Optical reservoir computing system and method of using the same

Abstract

An optical reservoir computing (ORC) system has a near-UV light emitting diode modulator (LED-M), a beam expander (BE), a fluorescer array (FA), an optical integrator (OA), a liquid crystal spatial light modulator (LC-SLM), and a photo-detector array (PDA). The LED-M receives an input electrical signal and outputs an optical signal passing through the BE, being made incident upon the FA, being processed in the OA, and being multiplexed onto the LC-SLM. “Non-Linearity” is introduced by overlapping responses to input signals by the FA. “High Dimensionality” is provided by the random but fixed time-wavelength multiplexing onto an imaging plane by a Fresnel-Kohler Integrator (FKI). “Fading Memory” is provided by different decay time constants of the fluorescers. A method of using the ORC system comprises the steps of minimizing an error function of difference between a measured state of the PDA and a target state of the PDA by a regression model.
