Spontaneous Parametric Down-Conversion [PDF]

open access: yesContemporary 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 ...

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.

Nanoscale Spontaneous Parametric Down-Conversion

OSA Nonlinear Optics 2021, 2021
We generate entangled photons via spontaneous parametric down-conversion (SPDC) in subwavelength films of nonlinear materials and all-dielectric nonlinear metasurfaces. The SPDC spectra reveal resonances: Fabry-Perot in the first case and Mie in the second case.

Spontaneous parametric down-conversion

Journal of Experimental and Theoretical Physics Letters, 2005
Spontaneous parametric down-conversion (SPDC) in media with no inversion center and the use of this phenomenon in the spectroscopy of natural oscillation states of a crystal lattice (i.e., optical phonons) are retrospectively described. We think that the SPDC spectroscopy method is estimated inappropriately and hope to again attract the attention of ...

Cryogenic Degenerate Spontaneous Parametric Down-Conversion

Optica Quantum 2.0 Conference and Exhibition, 2023
We show a HOM dip between degenerate signal and idler photons at (1559.33 ± 0.05) nm from cryogenic integrated SPDC in lithium niobate, compatible with superconducting detectors. This is enabled by precise control over the cryogenic phase-matching.

Interferometry of spontaneous parametric down conversion

Technical Digest. Summaries of papers presented at the Quantum Electronics and Laser Science Conference. Postconference Technical Digest (IEEE Cat. No.01CH37172), 2002
Summary form only given. The interference of spontaneous radiation emitted from two macroscopic regions (a nonlinear analogy of the Mach-Zehnder interferometer) is considered. The interferometer is based on two nonlinear crystals, excited in series by a common laser pump. The crystals are separated by a layer with an unknown dispersion law.

Quantum entanglement swapping with spontaneous parametric down conversion

SPIE Proceedings, 2003
Two remote parties that have never interacted each other can be entangled through entanglement swapping operation done by a third party. Currently existing entanglement swapping experiments are done probabilistically by postselection, i.e., once a successful swapping is verified, the resultant entanglement is destructed.

Significance of heralding in spontaneous parametric down-conversion

Physical Review A, 2014
Single photons exhibit nonclassical, counterintuitive behavior that can be exploited in the developing field of quantum technology. They are needed for various applications such as quantum key distribution, optical quantum information processing, quantum computing, intensity measurement standards, and others yet to be discovered in this developing ...

Producing multiple qubits via spontaneous parametric down-conversion

Conference on Lasers and Electro-Optics, 2021
We have designed Gaussian masks to subdivide the pump beam before passing it through a BBO. In this way, present an approach to possibly produce multiple entangled photon pairs through spontaneous parametric down-conversion (SPDC).
