摘要：

We demonstrate experimentally tunable control of the joint spectrum, i.e., waveform and degree of frequency correlations, of paired photons generated in spontaneous parametric down-conversion. This control is mediated by the spatial shape of the pump beam in type-I noncollinear configurations.
