  • METHODS AND APPARATUS FOR MULTI-PROBE PHOTONIC TIME-STRETCH SPECTRAL MEASUREMENTS
    Publication number: 20180003560
    Abstract: Methods and apparatus for multi-probe photonic time-stretch spectral measurements are described. Methods allow for capturing real-time and single-shot non-overlapping spectral bands from multiple probes simultaneously, using Time-Stretch Dispersive Fourier Transform (TS-DFT) systems combined with Wavelength Division Multiplexing (WDM) device.

  • Integrated-optic channel monitoring
    Patent number: 6822743
    Abstract: A device for measuring wavelength of an electromagnetic signal has first and second waveguides configured such that a portion of an electromagnetic signal transmitted through the first waveguide is separated from the remaining portion of the electromagnetic signal and is communicated to the second waveguide and is subsequently at least partially recombined with the remaining electromagnetic signal in the first waveguide after traveling a distance which is different from a distance traveled by the remaining electromagnetic signal in the first waveguide. A first sensor is configured to measure the power of the electromagnetic signal in the first waveguide after at least a portion of the separated electromagnetic signal in the first waveguide has been recombined with the remaining electromagnetic signal in the first waveguide.
