Entanglement, Complementarity, and Vacuum Fields in Spontaneous Parametric Down-Conversion [PDF]
Using two crystals for spontaneous parametric down-conversion in a parallel setup, we observe two-photon interference with high visibility. The high visibility is consistent with complementarity and the absence of which-path information. The observations

Classical model of spontaneous parametric down-conversion
We model spontaneous parametric down-conversion (SPDC) as classical difference frequency generation (DFG) of the pump field and a hypothetical stochastic “vacuum” seed field.

Spontaneous Parametric Down-Conversion in 4H-SiC Integrated Platform [PDF]
Abstract4H‐silicon carbide (SiC) has recently emerged as a promising material for nonlinear photonic integrated circuits, thanks to its low loss, wide bandgap, as well as strong second‐order () and third‐order () nonlinearities. Though its unique crystal structure allows versatile processes, spontaneous parametric down‐conversion (SPDC) still remains ...

Multimode Spontaneous Parametric Down-Conversion in a Lossy Medium [PDF]
We study the process of multimode Spontaneous Parametric Down--Conversion (SPDC) in the lossy, one dimensional waveguide. We propose a description using first order Correlation Functions (CF) in the fluorescence fields, as a very fruitful and easy approach providing us with a complete information about the final multimode state.

We study a calibration scheme for terahertz wave nonlinear-optical detectors based on spontaneous parametric down-conversion. Contrary to the usual low wavelength pump in the green, we report here on the observation of spontaneous parametric down ...

General simulation method for spontaneous parametric down- and parametric up-conversion experiments
Spontaneous parametric down-conversion (SPDC) sources are an important technology for quantum sensing and imaging. We demonstrate a general simulation method, based on modeling from first principles, reproducing the spectrally and spatially resolved ...

Sunlight-excited spontaneous parametric down-conversion for ghost imaging [PDF]
Ghost imaging (GI) has been under development for several years and is now achievable in both single- and multiphoton regimes with both quantum and classical light. Here, we address the experimental challenge of using sunlight as a pump beam to excite spontaneous parametric down-conversion and generate photon pairs.
