Controlled Frequency Entanglement of Photons in Type-II Spontaneous Parametric Down-Conversion
Ryōsuke Shimizu, Keiichi Edamatsu · 2009
We report broadband entangled photon sources that have control capability of the frequency entanglement. Directly observing the frequency correlation between the constituent photons, we demonstrate the biphoton sources consisting of frequency-correlated or frequency-anticorrelated photons.
