  • Temporal modes of electromagnetic radiation using nonlinear optical cavities and shaped laser pulses
    Patent number: 10871699
    Abstract: Apparatus include an optical cavity including an optical coupling portion situated to couple an optical signal input field to an intracavity optical signal field and an optical control input field to an intracavity optical control field, wherein the optical cavity includes a nonlinear optical medium that mediates a selective exchange of at least one predetermined temporal mode between the intracavity optical signal field and an intracavity optical register field based on a nonlinear phase-matched interaction between the intracavity optical signal, control, and register fields and selectable field characteristics of the optical control input field.

  • Linear optical sampling methods and apparatus
    Patent number: 7529481
    Abstract: An optical data signal can be sampled by linearly combining the optical data signal with optical sampling pulses, and delivering the combination to first and second balanced detectors. The optical data signal and the optical sampling pulse are configured to have a first phase difference at the first balanced detector and a second phase difference at the second balanced detector. Typically, a difference between the first phase difference and the second phase difference is configured to be about 90 degrees. In-phase and quadrature balanced detector outputs can be combined as a sum of squares to produce a linear sampling signal representative of data signal intensity, and the sample pulses can be configured to temporally step through the optical data signal so that a sampled representation of the optical data signal is obtained.
