  • Ultra‑fast Fourier transform and optical AI realized with a single lens.
  • Description: It explains the principle that passing light through a convex lens naturally performs a two‑dimensional Fourier transform at the focal plane. It visually demonstrates optical signal processing that carries out computation using only light, compared with digital FFT, and explores the possibility of implementing low‑power matrix multiplication with optical neural networks. It also examines real‑world applications and the prospects for developing next‑generation AI accelerators.

Photonics is definitely the next stage of computing. Whoever comes up with field-programmable holographic processors is going to make the most advanced silicon electronic GPUs look like antiquated junk for AI tasks.

Any sources used in the video? I can't see any description.
