Background and Review of Cavity-Enhanced Spontaneous Parametric Down-Conversion [PDF]
Journal of Research of the National Institute of Standards and Technology, 2019 Spontaneous parametric down-conversion (SPDC) in a nonlinear crystal has been a workhorse for the generation of entangled and correlated single-photon pairs used for quantum communications applications for nearly three decades.

Spatiotemporal correlations in spontaneous parametric down conversion
, 2014 Presented at the Solvay workshop “Bits, Quanta, and Complex Systems”. Brussels -Belgium, April 30 - May 3 (2008). Abstract: In most configurations aimed at generating entangled photons based on spontaneous parametric down conversion (SPDC), the generated pairs of photons are required to be entangled in only one degree of freedom.

Degenerate spontaneous parametric down-conversion in nonlinear metasurfaces
Optics Express, 2023 We propose a simple scheme of degenerate spontaneous parametric down-conversion (SPDC) in nonlinear metasurfaces or photonic crystal slabs with quasi-guided modes. It employs a band crossing between even- and odd-parity quasi-guided mode bands inside the light cone (above the light line) and a selection rule in the conversion efficiency of the SPDC ...

Spontaneous Parametric Down-Conversion from GaAs Nanowires at Telecom Wavelength [PDF]
EPJ Web of Conferences, 2022 We report on the generation of photon pairs at 1550 nm from free-standing epitaxially grown self-assisted micrometre long GaAs nanowires. The efficiency of the spontaneous parametric down-conversion process has a rate of 320 GHz/Wm normalized to the ...
