Abstract :
Based on the quantum behavior of entangled photon pairs generated via spontaneous parametric down conversion, this paper reviews the concept of effective two-photon wavefunction or biphoton wavepacket and emphasize the very different physics associated with the entangled two-photon system and with its "individual" subsystems. Experimental approaches for Bell state preparation, pumped by continuous wave and ultrashort pulse, and the propagation of biphoton wavepacket in dispersive media are discussed.
