Direct measurement of ultrafast temporal wavefunctions

چکیده
The large capacity and robustness of information encoding in the temporal mode photons is important quantum processing, which characterizing states with high usability time resolution essential. We propose demonstrate a direct measurement method complex wavefunctions for weak light at single-photon level subpicosecond resolution. Our realized by ultrafast metrology interference between under test self-generated monochromatic reference light; no external or complicated post-processing algorithms are required. Hence, this versatile potentially widely applicable state characterization.

Direct measurement of group delay dispersion in metamagnetics for ultrafast pulse shaping.
In this paper, we explore the use of magnetic resonant metamaterials, so called metamagnetics, as dispersive elements for optical pulse shaping. We measure both positive and negative group delay dispersion (GDD) values in a metamagnetic material using the multiphoton interference phase scan (MIIPS) technique and show pulse temporal profiles numerically. The results are compared with finite elem...
متن کاملDirect Simulation of Ultrafast Detonations in Mixtures
For nearly a century experimental measurements of the velocities of detonations in gases have been found in general agreement with those of the Chapman-Jouguet (C-J) hypothesis predicting velocities, relative to the burned gases, equal to the speed of sound in the burned gases. This was further supported by the Zeldovich von Neumann Döring (ZND) theories predicting Chapman-Jouguet velocities fo...
