“…Suitable conditions for generation of light with subPoissonian photon-number statistics are similar to those needed for observation of squeezed light and analyzed in detail in the report. This similarity has been elucidated in detail in [45,46] for three-mode interaction. It allows to use directly the results obtained for squeezed light also in the analysis of suitable conditions for the generation of light with sub-Poissonian photon-number statistics.…”

The public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing the burden, to Department of Defense, Washington Headquarters Services, Directorate for Information A waveguide made of LiNbO3 with a periodic linear corrugation on its surface is analyzed from the point of view of squeezed-light generation. It is shown that scattering of nonlinearly interacting optical fields caused by the corrugation improves efficiency of the nonlinear process under certain conditions. These conditions are found approximately analytically and confirmed numerically. The linear corrugation can be tuned both into the pump as well as second-subharmonic field in order to improve efficiency of the nonlinear process. The analysis provides a detailed understanding of the role of all parameters of the waveguide and this enables to specify optimum values of parameters to achieve the best values of squeezing. In pulsed regime the right choice of spectral modes is important to observe squeezing. These modes are found using the Bloch-Messiah reduction of the appropriate Green functions. 5a. CONTRACT NUMBER.

*Quantum pulsed second-subharmonic generation in a planar waveguide with a small periodic corrugation at the surface is studied. Back-scattering of the interacting fields on the corrugation enhances the nonlinear interaction giving larger values of squeezing. The problem of back-scattering is treated by perturbation theory, using the Fourier transform for non-dispersion propagation, and by numerical approach in the general case. Optimum spectral modes for squeezed-light generation are found using the Bloch-Messiah reduction. Improvement in squeezing and increase of numbers of generated photons are quantified for the corrugation resonating with the fundamental and secondsubharmonic field. Splitting of the generated pulse by the corrugation is predicted.

The optical parametric process occurring in a photonic-band-gap planar waveguide is studied from the point of view of nonclassical-light generation. The nonlinearly interacting optical fields are described by the generalized superposition of coherent signals and noise using the method of operator linear corrections to a classical strong solution. Scattered backward-propagating fields are taken into account. Squeezed light as well as light with sub-Poissonian statistics can be obtained in two-mode fields under the specified conditions
