Abstract

Abstract

Random projections of RF signals are obtained by modulating the signal onto an optical carrier and propagating through a multimode waveguide. These random projections are digitally post-processed to obtain the properties of unknown input signals within compressive sensing and reservoir computing systems.

Abstract

Abstract

We demonstrate recovery of Mackey-Glass waveforms and multi-frequency sinusoids using speckle-based reservoir computer. Neurons and RF waveforms drive a spatial light modulator imaged onto a multimode fiber. Fiber output is imaged onto a camera, digitally processed and fed back into the fiber through the modulator.
