Quasi-Phasematched Nonlinear Optics: Materials and Devices
Abstract
This program focused on the development of micro-structured nonlinear optical materials and quasi- phasematched devices based on those materials. The two material systems investigated, periodically-poled ferroelectrics, especially lithium niobate (PPLN), and orientation-patterned GaAs (OP-GaAs), enable nonlinear interactions impossible in conventional nonlinear media. The work included characterization of vapor- transport-equilibrated materials, enhancements in periodic-poling technology, and development of tight bends in proton-exchanged waveguides. After the materials characterization and improvements in process development, we fabricated new devices including OP-GaAs devices for broadband optical parametric generation (OPG) at mid-infrared wavelengths, bulk PPLN devices for soliton amplifiers, and PPLN reverse- proton-exchanged waveguide devices for quasi-group-velocity-matching, telecommunication applications and generation of nearly-transform-limited OPG. Supplemental MlPR funding from DARPA was used to support and purchase ceramic fabrication equipment for the fabrication of transparent laser host materials, supported primarily under ARO Grant DAADI9-02-1-0184.
