We present an experimental demonstration of the full control of the frequencycorrelations of entangled photon pairs. The joint spectrum of photon pairs iscontinuously varied from photons that exhibit anticorrelation in frequency tophotons that exhibit correlation in frequency, passing through the case ofuncorrelated photons. Highly entangled frequency-anticorrelated photon pairswere obtained even when an ultrafast laser was used as a pump. The differentkinds of correlations are obtained without changing neither the wavelength, northe nonlinear crystal.
