摘要：

A two-photon wave packet (a biphoton) produced by type-If parametric downconversion is studied in a simple beam-splitting experiment for its natural shape in space-time. The measured triangular shape of a two-photon correlation function is the signature of a rectangular-shaped biphoton. Inserting a birefringent sample into the beam causes a displacement of the vertex of the notch pattern, which can be used to measure the optical delay between the ordinary and the extraordinary rays in the sample with femtosecond resolution.
