Quantum-enhanced second harmonic generation beyond the photon pairs regime
Thomas Dickinson, Ivi Afxenti, Giedre Astrauskaite +8
Two-photon processes are crucial in applications like microscopy and microfabrication, but their low cross-section requires intense illumination and limits, e.g., the penetration d…
Unified space-time description of pulsed twin beams
Alessandra Gatti, Enrico Brambilla, Ottavia Jedrkiewicz
This work provides a mathematical derivation of a quasi-stationary model for multimode parametric down-conversion, which was presented in [Gatti et al., Sci. Rep. 13, 16786] with h…
Modeling the space-time correlation of pulsed twin beams
Alessandra Gatti, Ottavia Jedrkiewicz, Enrico Brambilla
Entangled twin-beams generated by parametric down-conversion are among the favorite sources for imaging-oriented applications, due their multimodal nature in space and time. Howeve…
Hot-spots and gain enhancement in a doubly pumped parametric down-conversion process
Ottavia Jedrkiewicz, Erica Invernizzi, Enrico Brambilla +1
We experimentally investigate the parametric down-conversion process in a nonlinear bulk crystal, driven by two non-collinear pump modes. The experiment shows the emergence of brig…
Engineering multipartite entangled states in doubly pumped parametric down-conversion processes
Alessandra Gatti, Enrico Brambilla, Ottavia Jedrkiewicz
We investigate the quantum state generated by optical parametric down-conversion in a medium driven by two noncollinear light modes. The analysis shows the emergence of…
Golden Ratio entanglement in hexagonally poled nonlinear crystals
Alessandra Gatti, Enrico Brambilla, Katia Gallo +1
This work analyses the quantum state of twin photons and twin beams generated by parametric-down conversion in a hexagonally poled photonic crystal,characterized by the simultaneou…
