(DARPA) Nonlinear Optics at Low Light Levels

Abstract

The principal accomplishments of this program were: 1)The use of slow light to demonstrate a source of biphotons with temporal lengths as long as four hundred nanoseconds and wavepacket lengths exceeding a football field. 2) The first observation of optical precursors at the single photon level. 3) The first electrooptic shaping and modulation of single photons. 4) The demonstration of the modulation of biphotons and the invention and demonstration of a Fourier technique for measuring the temporal length of biphotons by using fast modulators instead of fast detectors. 5) The prediction and first demonstration of a novel quantum effect that we have termed as nonlocal modulation, and 6) the demonstration of spread spectrum technology to allow the hiding and regeneration of single photons. These accomplishments would not have been possible without the joint support of the Air Force Office of Scientific Research and the Army Research Office.
