We present a first experimental test of the existence of Spontaneus Para-metric Up Conversion predicted in Ref. [3]. The measurement has been made using a ccd camera on the emission of a LiIO 3 crystal pumped by a 351 nm and/or a 789 nm lasers. We obtain an upper limit of 160 times on the ratio between intensity of Spontaneus Parametric Up Conversion and Spontaneous Parametric Down conversion.

متن کاملSpatial-to-spectral mapping in spontaneous parametric down-conversion
We put forward an approach for manipulating the spectral profile of entangled photon pairs. Such spectral properties are mediated by the geometry of noncollinear spontaneous parametric down-conversion and by selecting the appropriate spatial profile of the pump laser radiation. We show that one can translate spatial features imprinted in the pump beam into desired spectral profiles of the gener...
متن کاملStrong Spectral Entanglement in Spontaneous Parametric Down-Conversion
Photon pairs with a high degree of spectral entanglement have a very large capacity for carrying information. We describe methods for generating this type of entanglement and discuss applications. ! 2009 Optical Society of America OCIS codes: (270.5585) Quantum information and processing; (270.5565) Quantum communications. Spontaneous parametric down-conversion (SPDC) has proven to be a reliabl...
متن کاملMapping of periodically poled crystals via spontaneous parametric down-conversion
A new method for characterization of periodically poled crystals is developed based on spontaneous parametric down-conversion. The method is demonstrated on crystals of Y:LiNbO3, Mg:Y:LiNbO3 with non-uniform periodically poled structures, obtained directly under Czochralski growth procedure and designed for application of 1.064 μm-pumped OPO in the mid infrared range. Infrared dispersion of ref...
