Transverse Entanglement of Biphotons
Felix Just, Andrea Cavanna, Maria V. Chekhova +1
We measure the transverse entanglement of photon pairs on their propagation from the near to the far field of spontaneous parametric downconversion (SPDC). The Fedorov ratio, depen…
Detection of non-classical space-time correlations with a novel type of single-photon camera
Felix Just, Mykhaylo Filipenko, Andrea Cavanna +9
During the last decades, multi-pixel detectors have been developed capable of registering single photons. The newly developed Hybrid Photon Detector camera has a remarkable propert…
Tunable optical parametric generator based on the pump spatial walk-off
Andrea Cavanna, Felix Just, Polina R. Sharapova +3
We suggest a novel optical parametric generator (OPG) in which one of the down-converted beams is spontaneously generated along the Poynting vector of the pump beam. In this config…
Autonomous absolute calibration of an ICCD camera in single-photon detection regime
Luo Qi, Felix Just, Gerd Leuchs +1
Intensified charge coupled device (ICCD) cameras are widely used in various applications such as microscopy, astronomy, spectroscopy. Often they are used as single-photon detectors…
Compensation of anisotropy effects in the generation of two-photon light
Andrea Cavanna, Angela M. Pérez, Felix Just +2
We analyse a method to compensate for anisotropy effects in the spatial distribution of parametric down-conversion (PDC) radiation in bulk crystals. In this method, a single nonlin…
