Abstract
Extended phase-matching
conditions for spontaneous parametric down-conversion are examined.
By augmenting
the conventional phase-matching conditions, they permit the creation
of a class of frequencyentangled
states that generalizes the usual twin-beam biphoton state. An experimental
characterization of these
states is possible through interferometric coincidence counting.
