  • System and method for programmable nonlinear silicon photonic circuit
    Patent number: 11187963
    Abstract: According to various embodiments, an all-optical thresholder device is disclosed. The all-optical thresholder device includes a Mach-Zehnder interferometer (MZI) coupled to a Mach-Zehnder coupler (MZC). The MZI includes at least one microring resonator (MRR) and a first tunable element, where the MRR further includes a second tunable element. The MZC includes a third tunable element. The first, second, and third tunable elements are configured to control biases of the all-optical thresholder device to achieve a desired power transfer function.
    Type: Grant
    Filed: January 29, 2020
    Date of Patent: November 30, 2021
    Assignee: THE TRUSTEES OF PRINCETON UNIVERSITY

  • Ultra-Compact Planar Mode Size Converter with Integrated Aspherical Semi-Lens
    Publication number: 20200110219
    Abstract: An optical beam transformer includes a taper structure where the structure width is varied, an integrated aspherical semi-lens structure having a straight proximal end formed adjacent to a distal end of the taper structure to be in direct contact therewith, and a convex semi-lens section having a curved proximal end in direct contact with a curved distal end of the integrated aspherical semi-lens structure.
