Entanglement, Complementarity, and Vacuum Fields in Spontaneous Parametric Down-Conversion [PDF]

open access: yesAtoms, 2019
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

open access: yesPhysical Review Research, 2022
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]

open access: hybridLaser and Photonics Reviews
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]

open access: yesJournal of Modern Optics, 2010
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.

Towards terahertz detection and calibration through spontaneous parametric down-conversion in the terahertz idler-frequency range generated by a 795 nm diode laser system

open access: yesAPL Photonics, 2018
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

open access: yesSciPost Physics Core, 2023
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 ...

Full characterization of spontaneous parametric down conversion in non-ideal quarter-wavelength semiconductor Bragg reflection waveguide

open access: yesFrontiers in Physics, 2023
Entangled photons are important for testing foundations of quantum physics and are at the heart of quantum technology. Integrated photonics has overwhelming dominance in terms of density and performance, making it a promise route for scalable quantum ...

Sunlight-excited spontaneous parametric down-conversion for ghost imaging [PDF]

open access: diamondAdvanced Photonics
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.
