Separated Schmidt modes in the angular spectrum of biphotons
N. A. Borshchevskaia, F. Just, K. G. Katamadze +2
We prepare qudits based on angular multimode biphoton states by modulating the pump angular spectrum. The modes are prepared in the Schmidt basis and their intensity distributions…
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…
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…
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…
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…
