  • TUNABLE IN-POOL WAVEGUIDE AND METHOD
    Publication number: 20230082670
    Abstract: A photonics integrated circuit includes a first waveguide and a second waveguide. A portion of the first waveguide has a first cladding with a first refractive index. The second waveguide includes a second cladding with a second refractive index different from the first refractive index. Also disclosed is a test circuit for a photonics integrated circuit. The test circuit can be used to determine waveguide losses, and used to tune the waveguide losses.

  • ELECTRICAL AND PHOTONIC INTEGRATED CIRCUITS ARCHITECTURE
    Publication number: 20220390562
    Abstract: Disclosed herein are microelectronics packages and methods for manufacturing the same. The microelectronics packages may include a photonic integrated circuit (PIC), an electrical integrated circuit (EIC), and an interconnect. The interconnect may connect the EIC to the PIC. The interconnect may include a plurality of paths between the EIC and the PIC and the individual paths of the plurality of paths are less than 100 micrometers long.

  • Hybrid electro-active lens
    Patent number: 7019890
    Abstract: An electro-active lens is disclosed. The lens includes at least one electro-active cell to provide a lens having at least two focal lengths, the electro-active cell capable of adjusting its focal length based on voltages applied to the electro-active cell. The voltage is supplied by an alternating current source, including a flying capacitor circuit. The electro-active lenses reduce birefringence through the use of a single cholesteric liquid crystal electro-active cell.

  • Hybrid electro-active lens
    Publication number: 20040223113
    Abstract: An electro-active lens that may include first and second electro-active cells, the cells being adjacent to each other and, when in a resting state, oriented orthogonal to each other to reduce birefringence.
