Abstract
The interference of biphotons emitted during collinear parametric scattering from two spatially separated regions is investigated experimentally and theoretically. It is shown that in this case the phase of the interference is determined by the pump wavelength and there is no need to equalize the optical paths for radiation from different regions.Keywords
