Spontaneous parametric down-conversion [PDF]
Contemporary Physics, 2018 Spontaneous Parametric Down-Conversion (SPDC), also known as parametric fluorescence, parametric noise, parametric scattering and all various combinations of the abbreviation SPDC, is a non-linear optical process where a photon spontaneously splits into ...

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

Tuning curve of type-0 spontaneous parametric down-conversion [PDF]
Journal of the Optical Society of America B: Optical Physics, 2013 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 spatiotemporal structure of the spectrum by means of measurements and numerical ...

Classical model of spontaneous parametric down-conversion
Physical 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.

Surface spontaneous parametric down-conversion [PDF]
Physical Review Letters, 2009 Surface spontaneous parametric down-conversion is predicted as a consequence of continuity requirements for electric- and magnetic-field amplitudes at a discontinuity of chi2 nonlinearity.

Angular Schmidt Modes in Spontaneous Parametric Down-Conversion [PDF]
Physical Review A, 2011 We report a proof-of-principle experiment demonstrating that appropriately chosen set of Hermite-Gaussian modes constitutes a Schmidt decomposition for transverse momentum states of biphotons generated in the process of spontaneous parametric down ...

Observation of frequency-uncorrelated photon pairs generated by counter-propagating spontaneous parametric down-conversion [PDF]
Scientific Reports, 2021 We report the generation of frequency-uncorrelated photon pairs from counter-propagating spontaneous parametric down-conversion in a periodically-poled KTP waveguide.

Non separable Werner states in spontaneous parametric down-conversion [PDF]
Physical Review A, 2005 The multiphoton states generated by high-gain spontaneous parametric down-conversion (SPDC) in presence of large losses are investigated theoretically and experimentally.

Quantum Walk Topology and Spontaneous Parametric Down Conversion [PDF]
Optical and Quantum Electronics, 2016 In a recent detailed research program we proposed to study the complex physics of topological phases by an all optical implementation of a discrete-time quantum walk.

Towards spontaneous parametric down conversion from monolayer MoS2. [PDF]
Sci Rep, 2018 AbstractWe present a detailed study of the second order nonlinearity of 2D (mono-atomic layer) dichalcogenide MoS2, both in the visible and in the IR regime, and test its potential for spontaneous parametric down-conversion (SPDC), the amplification of vacuum fluctuations mediated by optical nonlinearity.
