Experimental realization of a tensor processor achieves 96.4% accuracy in DNN inference, suggesting novel optical computing capabilities.
We experimentally realize a wavelength–space–time multiplexed, high-parallelism optical tensor processor leveraging chromatic dispersion in a free-space diffraction grating and demonstrate batch DNN inference at 96.4% accuracy with optical energy consumption of 20 aJ/MAC.
