  • Patent number: 11874501
    Abstract: A photonic device configured to perform matrix vector multiplication operations at high frequencies is provided. The vector being multiplied by the matrix is defined by vector components at specific wavelengths. The device includes a first waveguide and a second waveguide. A series of tunable microring resonators (MRRs) are coupled to the first waveguide and to a respective series of passive delay rings (PDRs), which are coupled to the second waveguide. Each MRR/PDR pair defines a tunable matrix component (tunable weight) for a respective wavelength component of the vector. A series of controllable delay elements (CDEs) such as all-pass filters are coupled to the first waveguide, upstream from the tunable MRRs. Any tuning dependent group delay caused by the MRR/PDR pairs can be compensated by controlling the CDEs such that each wavelength components has substantially a same delay as the other wavelength components.

  • Patent number: 11865190
    Abstract: Lipid-based vesicles, typically herein called transfection competent vesicles (TCVs), configured to safely and efficiently deliver DNA, RNA, other nucleic acid and protein cargoes into target cells. The safety and efficiency are each, and both, achieved in part by eliminating organic solvents such as ethanol and detergents such as sodium dodecyl sulfate from the TCV loading processes (i.e., inserting a cargo into the TCV), TCV storage processes, and/or TCV delivery processes. The cargoes can also comprise nucleic acids complexed with a protein, such as a ribonucleoprotein (RNP). The systems, compositions, devices and methods, etc., herein, in some embodiments, can provide empty TCVs that can if desired be loaded at the bench without use of specialized equipment.
