Nonlocal pulse shaping with entangled photon pairs.
Nonlocal shaping effects in the time or spectral profiles of an entangled photon pair emerging from a pulsed parametric down-converter are observed by spectrally or temporally filtering one of the twin beams. In particular, we demonstrate the appearance of fourth-order ("ghost") interference fringes in the spectrum of one beam conditioned by photodetection at the output of an unbalanced Michels...
متن کاملTwo-dimensional nonlinear beam shaping.
We develop a technique for two-dimensional arbitrary wavefront shaping in quadratic nonlinear crystals by using binary nonlinear computer generated holograms. The method is based on transverse illumination of a binary modulated nonlinear photonic crystal, where the phase matching is partially satisfied through the nonlinear Raman-Nath process. We demonstrate the method experimentally showing a ...
متن کاملSpectral engineering of entangled two-photon states
We experimentally demonstrate an approach for manipulating the spectral profiles of entangled-photon pairs. The spectral properties are determined by selecting both the appropriate spatial profile of the pump laser radiation and the geometry of the noncollinear spontaneous parametric downconversion. Both spectra, the spectrum of the individual signal and idler photons, and the joint spectrum of...
متن کاملDispersion in Femtosecond Entangled Two-Photon Interference
Significant consideration has recently been given to the process of spontaneous parametric down-conversion in nonlinear crystals pumped by cw lasers [1–4]. The nonclassical properties of entangled two-photon light generated by this process have been used in many experimental schemes to elucidate distinctions between the predictions of classical and quantum physics [5]. Coincidence-count measure...
متن کاملProperties of pulsed entangled two-photon fields
The dependence of oneand two-photon characteristics of pulsed entangled two-photon fields generated in spontaneous parametric down-conversion on the pump-pulse properties (shape of the pumppulse spectrum and its internal structure) is examined. It is shown that entangled two-photon fields with defined properties can be generated. A general relation between the spectra of the down-converted fiel...
