DESCRIPTION:Abstract: Strongly-driven nonlinear optical processes such as s
 pontaneous parametric down-conversion and spontaneous four-wave mixing can
  produce multiphoton nonclassical beams of light which have applications i
 n quantum information processing and sensing. In contrast to the low-gain 
 regime\, new physical effects arise in a high-gain regime due to the inter
 actions between the nonclassical light and the strong pump driving the non
 linear process. Here\, we describe and experimentally observe a gain-depen
 dent group delay between the multiphoton pulses generated in a high-gain t
 ype-II spontaneous parametric down-conversion source. Since the group dela
 y introduces distinguishability between the generated photons\, it will be
  important to compensate for it when designing quantum interference device
 s in which strong optical nonlinearities are required.\n\nJoint work with 
 Guillaume Thekkadath\, Martin Houde\, Duncan England and Ben Sussman.\n\nC
