    Abstract: A method and device for sampling ultra-fast optical signals by generating a sampling signal comprising a train of short pulses and coupling the sampling signal together with an optical data signal to be sampled into a highly non-linear optical fiber. Four-wave mixing (FWM) occurs between the two signals resulting in a secondary signal output from the fiber consisting of pulsed components having energy proportional to the instantaneous power of points along the data signal. An analysis of this secondary signal can be carried out to create a normal trace or eye-diagram of the data signal.

    Abstract: A first polarization controller controls a polarization state of measured light. A second polarization controller controls a polarization state of an optical sampling pulse. The measured light and the optical sampling pulse having the polarization states controlled are input to an optical fiber. An optical signal output from the optical fiber is transmitted to a polarizer. A first control unit adjusts the first polarization controller based on the measured light output from the optical fiber and the measured light output from the polarizer. A second control unit adjusts the second polarization controller based on an optical sampling pulse output from the optical fiber. Waveform measurement is performed by using the output of the polarizer.

    Abstract: Plural electronic or optical images are provided in a streak optical system, as for instance by use of plural slits instead of the conventional single slit, to obtain a third, fourth etc. dimension—rather than only the conventional two, namely range or time and azimuth. Such additional dimension or dimensions are thereby incorporated into the optical information that is to be streaked and thereby time resolved. The added dimensions may take any of an extremely broad range of forms, including wavelength, polarization state, or one or more spatial dimensions—or indeed virtually any optical parameter that can be impressed upon a probe beam. Resulting capabilities remarkably include several new forms of lidar spectroscopy, fluorescence analysis, polarimetry, spectropolarimetry, and combinations of these.

    Abstract: The phase spectrum of an ultrashort pulse is measured based on two-dimensional spectral shearing interferometry with zero delay. The measurement is performed utilizing an optical source pulse from which is extracted a short pulse and from which a chirped component is generated. The chirped component is split into first and second chirped pulses. The first and second pulses are then mixed with the short pulse in a nonlinear medium to produce up-converted and spectrally sheared copies of the first and second chirped pulses, which are measured in a spectrometer. A plurality of path lengths for the first second chirped pulses is provide to generate delays and shift the relative positions of the first and second chirped pulses for additional measurements. The apparatus and methods are uniquely suited for characterizing single-cycle pulses.
