Anisotropically and high entanglement of biphoton states generated in spontaneous parametric down-conversion.
We show both theoretically and experimentally that biphoton wave packets generated via spontaneous parametric down-conversion can be strongly anisotropic and highly entangled. The conditions under which these effects exist are found and discussed.
