Abstract:

The central theme of the work on this contract has been development of techniques and ideas for the control of the waveforms of single photons and the extension of the concepts of nonlinear optics into the x-ray portion of the electromagnetic spectrum. Advances in the first portion of this work include the first demonstration of use of spread spectrum technology at the single photon level, and in particular the demonstration that it is possible to hide a single photon in an environment of a much higher density of photons with the same spectral power density, and the first demonstration of the technique of chirp and compress, again at the level of a single photon. Key contributions and advances in the hard x-ray portion of this work include The invention of a new technique for the generation of polarization entangled x-ray biphotons theoretical, and the demonstration of parametric down conversion in the Langevin regime. Recently, a paper describing the first demonstration of second harmonic generation at x-ray wavelengths has been submitted.
