Novel Frequency Conversion Phenomena Based on Poled Polymers ( Book )
2 editions published in 1997 in English and held by 2 libraries worldwide
The technology of second harmonic generation in channel waveguides made from poled polymers was developed for interaction geometries appropriate for (1) cascading and wavelength shifting, and (2) for wavelength demultiplexing. For fundamental beams which generate a harmonic along the same propagation direction, various phase matching geometries were studied which relied on periodically modulating the linear refractive index and/or the nonlinearity (QPM) in DANS. Although this approach with interdigitated poling electrodes did produce the best results ever reported in polymeric systems, it was not competitive with those in the ferroelectric QPM-LiNbO3. The best results were obtained using modal phase matching in which a low order fundamental waveguide mode was velocity matched to a higher order harmonic mode. By using multiple layers with successive layers poled in opposite directions, a figure of merit equal to LiNbO3 was achieved in the polymer DR1. However, the large losses at the second harmonic reduced the effective sample length and hence the absolute conversion efficiency. For oppositely propagating fundamental inputs, a geometry appropriate to demultiplexing, alternatively poled layers led to the largest conversion efficiencies for any material system for second harmonic beams radiated normal to the waveguide surfaces.

Elastic Properties of Metallic Superlattices. Revision ( Book )
1 edition published in 1994 in English and held by 1 library worldwide
This Final Report describes some of the significant results from our research program on the elastic properties of metallic multilayers and superlattices. The elastic properties of composition-modulated metallic superlattice films have received considerable attention over the past fifteen years following the initial reports of anomalous enhancements of some elastic moduli as measured by the bulge tester method. For example, it was reported that the Ag/Pd system exhibited an increase of the biaxial modulus of up to 500%. However, more recent measurements failed to reproduce such large enhancements of elastic moduli in the systems for which the elastic anomaly was originally measured. The elastic anomalies observed in subsequent experiments were considerably smaller, although they showed a functional dependence on lambda with either stiffening or softening taking place in different material systems for lambda in the range of approx. 25-40 A. In apparent contrast, some Brillouin light scattering (BLS) measurements have shown a softening of the shear elastic constant C sub 44 in some bcc/fcc systems, although a stiffening was found in Au/Cr. Because of these apparent contradictions, coupled with the importance of this problem, we initiated a program with ONR funding to investigate these effects. In this report, we review some of our significant results obtained with ONR funding, on the structural and elastic properties observed metallic superlattice films.

Nonlinear Optics in Thin Films ( Book )
1 edition published in 1989 in English and held by 1 library worldwide
Two nonlinear phenomena with the potential for locking together two waveguides/lasers have been examined theoretically. Phase conjugation of a plane-wave incident field onto a waveguide supporting two guided pump beams is a potentially useful phenomenon. This process can be very power efficient because of the strong spatial confinement of the pump beams. Multi-reflection effects within the guiding film lead to oscillations in the signal with increasing waveguide thickness and incidence angle. Coupling between two waveguides can be achieved by the exchange of spatial solitons when a self-focusing medium is used between two parallel waveguides. Model calculations based on the powerful Beam Propagation Method have indicated transfer efficiencies as large as 80 percent.
