Wavelength-space-time multiplexed,high-parallelism,free-space diffraction grating

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.
