  • Integrated optical field sampling platform
    Patent number: 12287239
    Abstract: Some aspects are directed to an all-on-chip, optoelectronic device for sampling arbitrary, low-energy, near-infrared waveforms under ambient conditions. This solid-state integrated detector uses optical-field-driven electron emission from resonant nanoantennas to achieve petahertz-level switching speeds by generating on-chip attosecond electron burst. Also disclosed is a cross-correlation technique based on perturbation of local electron field emission rates that allows for the full characterization of arbitrary electric fields down to 1 femtojoule, and/or on the order of 500 kV/m, using plasmonic nanoantennas.
    Type: Grant
    Filed: September 10, 2021

    Assignees: Massachusetts Institute of Technology, The Regents of the University of California, Deutsches Elektronen-Synchotron DESY
    Inventors: Marco Turchetti, Mina Bionta, Felix Ritzkowsky, Yujia Yang, Dario Cattozzo Mor, William Putnam, Franz X. Kaertner, Karl K. Berggren, Phillip Donald Keathley
