  • Wavelength-scale optical parametric oscillators
    Patent number: 11467470
    Abstract: An OPO including a resonator comprising a material having a nonlinear susceptibility generating an output electromagnetic field in response to a pump electromagnetic field inputted into the material. The output electromagnetic field has one or more output wavelengths longer than one or more pump wavelengths of the pump electromagnetic field. The resonator has dimensions less than, or on the order of, the one or more output wavelengths in free space.
    Type: Grant
    Filed: November 9, 2020
    Date of Patent: October 11, 2022
    Assignee: CALIFORNIA INSTITUTE OF TECHNOLOGY
    Inventors: Alireza Marandi, Saman Jahani
  • PARTICLES WITH OPTICAL METAMATERIAL SHELLS
    Publication number: 20210269708
    Abstract: A metamaterial shell architected on a core particle (comprising organic or inorganic material) so as to form a novel class of structurally hierarchical particle that has degrees of freedom in design parameters stemming from effective optical response of the metamaterial shell and from the electromagnetic modes in the core to elicit optical behaviours that are not easily achievable and designable in particles having simpler or smoother geometries.

  • Light confining devices using all-dielectric metamaterial cladding
    Patent number: 9274276
    Abstract: An all-dielectric metamaterial cladding is provided that can strongly confine light inside conventional low-index dielectric waveguides for use with photonic integrated circuits and nano-photonic devices. A class of metamaterials with dual electric and magnetic anisotropy along with giant birefringence can provide the ideal quasi-transverse electromagnetic mode propagation inside a glass core. A Transformed Cladding Waveguide can show an order of magnitude decreased cross-talk as compared to conventional waveguides.
