  • Integrated photonic encoding systems and methods for high speed and low power image processing
    Patent number: 12631554
    Abstract: A method performed by a photonics processing system includes encoding an input vector into first optical signals; performing an optical scattering of the first optical signals to form second optical signals, the optical scattering implementing a matrix multiplication of the input vector by a quasi-random matrix; detecting at least a portion of the second optical signals representing an output vector; and encoding the second optical signals in an electrical representation of the output vector.

  • Efficient ultrathin all-dielectric nonlinear optical device
    Patent number: 11314145
    Abstract: An apparatus and method are provided for generating harmonic light from a pump beam that is impinged on a metasurface comprising a plurality of all-dielectric resonator bodies. A multiple quantum well structure formed in each resonator body includes asymmetric coupled quantum wells having intersubband transition frequencies that couple to Mie resonances of the resonator bodies.
