One highly desired improvement for neutron sensing is an imaging neutron detector with high two-dimensional spatial resolution and a large detector area. At present, achievable real-time neutron imaging detector resolution is only about 1 mm. The innovation proposed is to adapt for neutron imaging the high spatial resolution Microchannel Plate (MCP) detector technology so widely used for detecting ...

Phase I seeks to develop lossless beam splitters in a planar integrated optical waveguide form for optical signal processing. We propose to construct lossless beam splitters based on a planar integrated optical waveguide form for the applications at 1.55 um. The proposed device consists of a beam splitter part and an optical amplification part. The device will be built on Er-doped fluoride glass f ...

NZ Applied Technologies proposes to develop plasma-enhanced metalorganic chemical vapor deposition (PE-MOCVD) to create optically clear single crystal films of several unexplored ternary nitride semiconductors to study their nonlinear optical properties, and to use them for frequency doubling of visible and near IR lasers into wavelengths ranging from green to violet. Ternary nitrides appear to be ...

The III-V nitride semiconductor family affords many unique properties which make these materials attractive candidates for producing electronic and optoelectronic devices. Much progress has been made in epitaxial thin film growth of nitrides using metalorganic chemical vapor deposition (MOCVD) and molecular beam epitaxy (MBE) during the last decade. These efforts are hindered by the lack of lattic ...

Parallax Research Inc. proposes to develop practical collimating optics for soft x-ray lasers and elemental analyses applications. Although there is no new physics involved in the operation of these optics, the ability to fabricate them economically is a recent innovation. These optics are intended to accept broad energy bandwidths of low energy x-rays diverging from a small source and re-direct t ...

Phosphides are growing in importance in the area of semiconductor, photo-voltaic, solar energy, microwave and optoelectronic devices. Indium phosphide is a well known semiconductor with application as a laser diode in fiberoptic communication and as a substrate for MMIC and MAFET devices for ultrahigh speed communication, computing and integrated electro-optics. InP also displays the photorefract ...

To date, studies of photoluminescence (PL) from mesoscopic semiconductors have focused on the size of the quantum dots. This effort places equal emphasis on the details of the nonlinear bonding dynamics of the elements comprising the dots. Nanotextured materials with nonlinear bonding dynamics develop energy localization phenomena that allow for selective excitation of vibrational modes that relax ...
