Experimental requirements for entangled two-photon spectroscopy
Stefan Lerch, André Stefanov
Entangled two-photon spectroscopy is expected to provide advantages compared with classical protocols. It is achieved by coherently controlling the spectral properties of energy-en…
Properties of upconverted entangled broadband light
Stefan Lerch, André Stefanov
We experimentally investigate the properties of light generated by the sequential processes of spontaneous parametric downconversion followed by upconversion. By interfering the up…
Observing the transition from quantum to classical energy correlations with photon pairs
Stefan Lerch, André Stefanov
We experimentally demonstrate a method to control the relative amount of quantum and classical energy correlations between two photons from a pair emitted by spontaneous parametric…
Tuning curve of type-0 spontaneous parametric down-conversion
Stefan Lerch, Bänz Bessire, Christof Bernhard +2
We study the tuning curve of entangled photons generated by type-0 spontaneous parametric down-conversion in a periodically poled KTP crystal. We demonstrate the X-shaped spatiotem…
