摘要： A method and a system for generating a hyper-entangled high-dimensional time-bin frequency-bin state, the method comprising generating a hyper-entangled state composed of a time-bin and frequency-bin encoded state, and individually modifying at least one of: i) the amplitude and ii) the phase of the state components at different frequency-bins and different time-bins of the hyper-entangled state. The system comprises a non-linear medium exited with multiple pulses in broad phase-matching conditions, a frequency mode separator and an amplitude/phase modulator, the frequency mode separator temporally and spatially separating frequency modes of the hyper-entangled state, the amplitude/phase modulator individually modifying at least one of: i) the amplitude (and ii) the phase of the state components at different frequency-bins and different time-bins of the hyper-entangled state.

摘要： A system and a method for phase extraction of a multi-path interferometer, the method comprising generating a reference signal of a coherence length longer than an arm length difference of the multi-path interferometer; splitting the reference signal into a frequency shifted reference signal and an unshifted reference signal; recombining the frequency shifted reference signal and the unshifted reference signal into a polarization- and frequency-multiplexed reference signal, and feeding the polarization- and frequency-multiplexed reference signal to the multi-path interferometer; detecting frequency shifted and unshifted output signals of the multi-path interferometer; and determining the interferometer phase from the detected signal.

摘要： A system and a method for generating tunable ultrafast optical pulses, the method comprising spectral broadening of a laser input beam by propagating the laser input beam in a nonlinear medium of a third-order nonlinear susceptibility χ(3), yielding an output laser spectrum; and one of: i) selecting at least one portion of the output laser spectrum, yielding an output pulse different than the input pulse and centered at a different frequency; ii) temporal compensation and spatial spreading of spectral components of the output laser spectrum; selecting two pulses at two different frequencies; and nonlinearly mixing the two pulses together in a first second-order nonlinear susceptibility χ(2) nonlinear crystal into a third pulse centered at a frequency which is a difference between the frequencies of the first two pulses; and iii) dividing output laser spectrum into a pump beam and a probe beam, directing a pump pulse to a third second-order nonlinear crystal for THz radiation generation; and directing a probe pulse to a third second-order nonlinear crystal for THz radiation reconstruction.

摘要： A method and system based on spectral domain interferometry for detecting intense THz electric field, allowing the use of thick crystal for spectroscopic purposes, in order to makes long temporal scans for increased spectral resolutions, and overcoming the limitation of over-rotation for presently available high power THz sources. Using this method and system the phase difference of approximately 8898π can be measured, which is 18000 times higher than the phase difference measured by electro-optic sampling (π/2).
