  • Highly scattering metasurface phase masks for complex wavefront engineering
    Patent number: 10732437
    Abstract: Complex wavefront engineering is realized through a random metasurface phase mask backed by a phase-only spatial light modulator. The metasurface consists of an array of subwavelength nanoscatterers which give the metasurface a pre-arranged disorder. Since the transmission matrix of the disordered metasurface is known, there is no need for extensive characterization measurements which are instead required in standard disordered optical devices.
    Type: Grant
    Filed: April 19, 2018
    Date of Patent: August 4, 2020
    Assignee: CALIFORNIA INSTITUTE OF TECHNOLOGY
    Inventors: Mooseok Jang, Yu Horie, Atsushi Shibukawa, Andrei Faraon, Changhuei Yang

  • Optical focusing inside scattering media with time-reversed ultrasound microbubble encoded (TRUME) light
    Patent number: 10203274
    Abstract: A method for irradiating scattering medium, including modifying a particle's response to electromagnetic radiation irradiating the particle in a scattering medium, wherein the electromagnetic radiation is scattered by the scattering medium, and modulated by the modifying, into scattered electromagnetic radiation comprising a scattered field; forming a phase conjugate field, wherein the phase conjugate field is a phase conjugate of the scattered field; and irradiating the scattering medium with the phase conjugate field, wherein the phase conjugate field forms a focus at a target defined by the particle.
