Control of the frequency correlations of entangled photons to produce a pure heralded single photon source
John Fredy Suárez-Pérez, Alejandra Valencia, Mayerlin Núñez Portela · Latin America Optics and Photonics Conference · 2018
A heralded single photon source is implemented from a spontaneous down conversion process. Frequency correlations between photon pairs are controlled by spectral filters. Heralded efficiency and purity of single photons are measured under different conditions.
