This Small Business Innovation Research Phase I program will determine the practicality of increasing the second harmonic (SH) output of frequency doubling devices by at least 5 times current gutput powers. Altos has demonstrated in preliminary experiments have a 2 times to 3 times increase in SH output by creating thermal gradients across the waveguide structures used to frequency double the lase ...

Anholt Technologies proposes to develop a low cost replacement aircraft Idoor. Preliminary analysis indicates Anholt Technologies' design, using Cpultruded stiffeners, flat panels and advanced adhesion techniques Jpossesses the required structural strength at a significantly reduced end Iitem cost. Anholt Technologies proposes to design, fabricate and test a Frepresentative stiffened structu ...

AstroPower proposes to develop a new ultra-thin gallium arsenide solar cell for space applications, that will result in significantly higher performance compared to conventional gallium arsenide and silicon solar cells. This design incorporates a "floating" junction on the front of the ultra-thin solar cell and a collecting junction at the back of the device. This design will significantly decreas ...

AstroPower proposes to develop high performance, room temperature, mass-producible, low-cost infrared detectors using liquid-phase heteroepitaxy of lattice-matched InGaAsSb and AlGaAsSb on GaSb substrates. The structure of these detectors will be a Separate Absorption and Multiplication Avalanche Photodiode (SAM-APD). This structure has proven to be an effective means of producing large gain in ...

We propose exploratory development of new epitaxial growth technologies for low-defect GiN epitaxial structures and surrogate substrates. A significant feature of our approach is epitaxial latval overgrowth for "defect filtering." We present arguments that such epitaxial lateral overgrowth will lead to GaN material of unprecedented quality with respect to defects, stress, and purity. In the Phase ...

The threat of terrorist or military attack using biological or chemical warfare agents is one of the largest concerns to U.S. military forces. Development of defense initiatives that can be implemented to decontaminate personnel, equipment and buildingsare required to counter the effects of such an attack. A series of dendrimer-quaternary ammonium compound (QAC) biocides have been identified that ...

The success or failure of military operations increasingly depends on situation awareness. Critical to situation awareness is the knowledge of the precise position and heading of weaponry and personnel. There is a need for navigational systemsindependent of external sources and signals that would provide information about the position or movement of weaponry and personnel. Elsicon proposes a fu ...

In this effort we proposed to develop an integrated software environment for the rigorous electromagnetic analysis and design of diffractive optical elements (DOEs). To this end, we will develop a user-friendly graphical user interface (GUI) specificallygeared towards DOEs; we will refine, expand and integrate our suite of electromagnetic analysis tools based on the finite-difference time-domain ...

A nearly universal trend in modern technology is the continued integration of systems, and their associated devices, on decreasingly smaller scales. While this has led to personal computers that offer more functionality and faster computational speeds, ithas also spurred the development of hybrid optoelectronic systems on a chip (SOCs). Currently, such SOCs are receiving significant interest fro ...

We propose using our unique, self-reinforcing, rigid-rod, polyparaphenylene-based thermoplastic for fabricating low-cost, lightweight scuttles and hatches. This thermoplastic, named Parmaxr Self-Reinforced Polymer (
