  • Heterogeneous integration of an electro-optical platform
    Patent number: 11675126
    Abstract: A hybrid photonic integrated circuit and a method of its manufacture are provided. A SiP functional layer is fabricated on an SOI wafer. A lithium niobate thin film is bonded to the SiP functional layer. The silicon handle layer is removed from the SOI wafer to expose buried oxide, and at least one III-V die is bonded to the exposed buried oxide. In embodiments, at least one waveguiding component is fabricated in the SiP functional layer. In embodiments, the SiP functional layer comprises a top waveguiding layer.

  • System and method for bound state in continuum laser sources
    Patent number: 11152768
    Abstract: Systems and methods according to present principles provide, at room temperature, a bound state in the continuum laser that harnesses optical modes residing in the radiation continuum but nonetheless may possess arbitrarily high quality factors. These counterintuitive cavities are based on resonantly trapped symmetry-compatible modes that destructively interfere. Such systems and methods may be applied towards coherent sources with intriguing topological properties for optical trapping, biological imaging, and quantum communication.

  • System and method for using exceptional points in plasmonic nanostructures for sensing, communication and imaging
    Patent number: 10942376
    Abstract: Systems and methods according to present principles provide ways to construct and use tunable exceptional point (EP) singularities in three-dimensional plasmonic nanostructures. Such structures have applications in sensing, communication, imaging, and other fields where, e.g., determining sub wavelength features of interest is of value.
